    The next thing to examine is the way the caliper "grips" the disc. One way to do this is, without using the brakes, bring the car to a standstill and get under the car as best you can and have an assistant apply the brakes firmly. Note the way that the caliper moves. If there is little no discernible movement AND the pads are wearing evenly then all is well - i.e. the caliper is aligned squarely with the disc. If they twist a bit when the brakes are applied then there's work to be done!

    Common culprits are: a twisted brake hose, a bent caliper brackets, worn or bent caliper locating arms and incorrectly installed anti-rattle rubbers. The same applies to the rears but also check for wear in the wheel bearings (as mentioned above) and - this is a biggie - the flat plate that locates the caliper via a pin on the back of the axle carrier tube is bent.

    These are often bent because over the years people tend to remove the caliper without slackening the big brass nut on the handbrake adjuster far enough off. If these are bent then they hold the caliper at an angle off the disc and some braking effort is required to realign the caliper before pressure is applied to the pads.

    P
    Ok Exfrogger, thank very much for all your advices. I will begin tomorrow and check all things up. Is it important that the cars is standing on all four wheels? I have a lift in my garage, and it's much easier to lift the car.
    Thanks
    Gösta

    Default Bittersweet

    This past weekend was Classic Car Racing again and it all happened at Hampton Downs in NZ. This track is becoming a favourite track for many. Skid pan in the middle is now complete and they have just finished the pits as well. It is a pity that you have to pay for it separate from your entry fee that is always too much for a financially disabled guy like me.
    As mentioned before, I was equipped with the new Big Brakes and that was going to be a huge test event. The pads I am using are Pagid that is about 33% cheaper than the Ferodo S3000 pads.
    Saturday morning me and Johan set off to Hamptons. Practice started for us and I took it very easy on the first section. I was disappointed at first but soon realized that the brakes improved very much with a little bit of heat. Starting the 2nd lap I was on speed and the testing started. Now I can lock the brakes very easy so that is something I will have to get used to. Our 10 mins practice time equates to about 4-5 laps. Everything felt good and my smile went right around. When I got the lap times from race control my jaw hung open. I have improved my previous best of 1:27.5 to 1:26.5 on the 2nd lap! And my second best was a 1:26.8. That is all they give you.
    Johan went out trying very hard, so hard that he spun out on every lap except 1. This resulted in a bad grid position unfortunately.
    Race 1 Saturday afternoon came and I started 13th on the grid of 26. The car was flying and my old competition in the form of a silver 3000cc Marcos Volvo was hauled in and left behind on the second lap, and with ease. Then the bitter started. I lost power on about the 6th lap and everybody came flying past. I retired to the pits and started the investigation. It ended in a blocked muffler! I took it home on Saturday night and did a quick fix with what I had available. Sunday morning started with 2 flying laps and then the power faded away and backfired badly. Some more investigation and this time it was more serious. Valve clearance on no3 exhaust was 0.100”. I suspect a failed cam follower will be my find when I open the motor. The end of the weekend.
    Race 1 Saturday for Johan was very good. He changed fuel loads and tyre pressures and found the car handling so good he recorded his best ever times as well. He improved from a 1:31.5 to a 1:28.8. He was going so good that his brakes failed (boiled) on the last lap as well and then he cruised back to the pits. A DNF as well but with a huge smile. Then on Sunday morning he started of flying the first couple of laps and then the car died in his arms. After the race they towed him back and we started the investigation. The pickup for the Megajolt on the crank had the wires fallen off. He plugged them back and the car fired back into life again. Then I asked him “what have you done to prevent that happening again?” He responded with a “gave them more slack, cable tie to tight.” The 2nd race started Sunday Afternoon and he went flying for 2 laps and then the car died again. After the race he dived under the car and found the little wires pulled out again. He plugged them in again and drove back to the pits. When we left for home last night he still wasn’t talking to himself!
    This is the in car camera footage of me on Saturday morning when I had my brief moment of happiness and then the blocked muffler stepped in and you will see all the cars passing me on my way to the pits.
    I have not edited it so there might be a slight delay at the start before the lights start coming on. Again sorry for the bad sound.

    I had a set JP Pistons forged for Kermit and they are great.

    No problems with a fully balanced nitrited crank. The lower oil control ring certainly helped to avoid scrubbing. The skirts have no evidence of wear. The crank case pressure is well within specifications.

    Hi All,
    I found my problem tonight and it is a valve seat that came out and went scew. so the valve couldn't close.
    So it is fortunately something very small and should be ready for the next race.

    Default Last race of our Series.

    Hi All,
    Today was the last of our series called ERC (European Racing Cars) and we will have our year end function next Saturday.
    It was very busy because what we normally did over 2 days previously happened all today.

    With my cylinder head back on and equipped with new valve seats I was keen on doing a full race with the new big brakes.
    We set off for timed practice runs on a very wet track and with these potent brakes I had several huge lock ups. This is something I have to get used to. Maybe I will do a few Winter series races to get the hang of the new brakes on the wet. Needless to say, my times was bad which put me 13th on the grid of 29 cars.

    We started the 1st race and as usual I overtook a few cars from the start line. On turn 2 with all the cars still in close vicinity of each other 2 cars rubbed wheels and caused the one to do two 360's in that cluttered piece of road. How the others missed him I can't tell, but he escaped with just the rub marks. I had a few options to avoid this carnage and when I came out on the other end I was in 4th position! This started to be the race of my life and luckily by now the track was dry as well. The car 's handling is just magic and I can go even deeper into the corners before braking. If you have seen the previous Youtube clips you will notice that with the standard brakes it was possible to outbrake almost all other cars. Now even better. Two of the fast guys that was involved in that turmoil caught me and passed me with the end result being 6th overall. I am very proud of this out of 29 cars. Me and Johan has the oldest cars on the track and the smallest engines except for one guy that claims his Escort is 1300. Well maybe it is. That makes our cars the second smallest on track.

    The second and third races started and this is on a handicap. I don't do that well in these races because the traffic becomes hairy and luck plays a big roll in it as well. But I was up there mixing it with the bigger boys...... I like to brag!

    I will have some footage up on Youtube later this week and you can decide for yourself.

    This season was good for me although I had my ups and downs. At the 1st race in September last year my best was a 1min30sec and that has improved to my best lap today at 1min25.05 sec. That is an improvement of about 166 meters per lap calculated at my average speed.

    Below is a copy of the cars entered today. The results was: 1st car 122, 2nd car 41, 3rd car 146, 4th car 71, 5th car 68, 6th car 866, 7th car 42, 8th car 461, 9th car 833, 10th car 20.

    Hi,
    Thank you for the comments.

    Schlitzaugen, There is photographers around the track but I don't know if they are for certain individuals or in general. I had my car in the Classic Car Magazine twice and then in the "Groundsky" and "Rollingwheels" web site.

    Default Youtube update.

    Hi All,
    Follow the link to the youtube clip of Saturday's race. There are quick cars and they normally overtake me on the straight. I do not have enough top end although the 535i BMW and Porsche do have to make hay and they can't slack down at all. Take note of the spin that I was talking about on turn 2 just after the start. I thought it was more hectic than seen on the clip but it helped me a lot.

    I mounted the camera just behind my head. I can't tell if this is the better position or should I leave it on the A-pillar as the older ones?

    Top gear racing. Good stuff. I reckon camera position just behind your head is best.

    Great shot Frans. Nice angle to show the front wheel of the Esky off the ground in corners.

    Your little beast is really amazing.

    Frans, i had to watch that with the head phones on as everyone was watching a film, and am so glad that i did. It sounds so much better, nice and loud with the plugs in your ears, it even felt like i was in the car with you. I like the camera position but for us fans out here could you also put a mirror for us, so we can see who's up your arse (just a thought).

    Prize giving!!

    Me and Johan attended the year end prize giving last night and we enjoyed a superb buffet dinner. That is about all we won.

    Our points accrued through the year were released (they don't give points out during the season because drivers can get desperate and cause havoc) and we are pleasantly surprised.

    Out of 73 entered I came 12th and Johan 30th which is not bad taking into consideration that he ran bearings twice and lost the timing pickup toothed wheel twice as well.

    I will post again on this thread if we do a Winter series but otherwise our seasons opener will be towards end September.

    Regards
    Frans.

    Default Muffler time

    Hi All,

    This last 2 weeks were muffler weeks. In the "lost in 2010" period I had pictures up of the extractor and muffler that was home built. The muffler being all alloy, by Ross, because of the specific ID and length required by the calculation. That was a test that failed and as mentioned in a few threads back it blocked during one of the races.

    So last week I took it of and cut it open (pic2) and took all the intestines out. The reason for failure was heat (pic3). It was almost OK because the inner alloy pipe melted only at the inlet, 100mm into the muffler part. Further down it was OK. The alloy broke up in 50c pieces and about another 150mm the pipe was non existing and that was where the fibre wool came out to block it.

    I phoned around for 44mm ID perforated tubing but could find any diameter except 44mm, and because the calculation say 44 I decided to get 44mm ID exhaust pipe and make my own perforated pipe (pic4). That was boring! To get mild steel in the alloy box I had to weld a flange (pic5) on at the one end and make an alloy end piece (pic6) that bolts to the flange (pic7). Then weld the alloy end piece onto the outer and there we have solved our problem. I found some muffler blanket at a Honda motorcycle dealer for $29.00 as seen in the picture(pic8). That will be wrapped around the perforated pipe and pushed into the outer pipe and then all will be welded closed.

    I hope to finish at the end of the week and post the final pictures.

    Regards
    Frans.

    The Muffler blanket you got, is it a ceramic fibre blanket?
    Just wondering, because thats what i used to wrap my extractors and I'm hoping it's what you have.

    I wouldn't know. It is very soft and it feels like a duvet. It is not glass because I forced my hand in between and split it in half and it didn't hurt afterwards. It is what they use in Quads and bikes mufflers at the Honda workshop.

    Complete and tested.

    The muffler is now complete. Ross welded the 2 ends on and then I welded the flange at the end. I now have and alloy outer and mild steel inner.

    I took the car for a test drive and the sound is very acceptable.

    Regards

    What Harry and I want to know is how are you going to get more hp to compensate for the heavier muffler?

    I will take the responsibility of that on myself.

    Laxative on the day before the race and a sedative on the race day:-)

    Don't you start as well I had so much sh!t from Ross about that damn Truimph but I am proud to say that on the 7th of May I out qualified and out raced him

    They are 2000cc 16 v motors similar to that used by Saab and that one is worked and running twin Webers and....and...

    (I have to have an excuse)
