Well I'll try one more post as a see how it goes. we have all posted a lot of "how to's" on here only to have it all gone. ..anyway........ I have been gathering components for my brake upgrade. I ended up with the following 307 HDI calipers - from wreckers 307 HDI discs - new 283mm 406 23.81mm master cylinder Lucas / TRW pads

After a good clean up, I am ready t put them on tomorrow. I will post more pics tomorrow as I work through the job
 
I'd highly recommend doing something to the rear brakes now... As they will basically be doing nothing with the increase in master size.
 
Hey DRTDVL, you have done this upgrade? I was thinking it would be the opposite. With the increase in MC size, i will be pushing more fluid into a smaller (than the front brakes) brake piston, thus activating harder?

I do have plans for the rears but really need the front doing first. When the 16v went in, all I could afford was to machine the discs and get a cheap pad. When I took the wheel of last night, I noticed the disc has hardly been used so I'm thinking pads are to soft of the MC is not functioning correctly. (or air still in the line)

In a perfect world, I could take the front calipers and discs from the front & put them on the rear but that wont happen.

I am also thinking that I refurbish the rear brakes with new discs and pads, and remove the compensator so they receive a greater line pressure but I have not heard of this being done.

I will suck it and see for the first few months.
 
:2cents: i got my brakes off a C4 Citroen 2.0l petrol which are the same as the 307 brakes. the caliper retaining bolts required a T55 torx socket which i got from repco for around $10. i also used threadlock on the bolts.
 
Hey mate,

This is the same setup I had on my 205gti6. MASSIVE improvement over standard. You will be impressed.
 
aaww thanks guys. I am half way through it and everything is fitting so well.
 
Hey can I ask you guys what you did with the flexible brake line. The 205 on seems a bit short now.

If I route it around the back of the strut it's ok but to short for it's normal position.

Thanks,

Moo
 
Omg!

Wow what a difference. Just hang on a tick 'till I can put my face back on!

Easiest mod I have ever done. I was picturing that I would have shims to make, brackets to engineer but no, it all went straight on. (as you can tell I'm a big believer in Murphy!)

I bled the MC before it went on the car. I still feel a little bit of sponge but i will take it for a good run to bed in tomorrow.

The warning about the inner wheel balance weights is correct. There is no room for them on the inside of the rim

I hate the disc position screws!

For some reason, people seem to think they are important and do them up really tight and use threadlock on them as well.

Why? So you have the pleasure of removing them with an easy out.

Thanks for the posts :cheers:
 
They're bloody big brakes on a 205!

I have these on my series 2 Xsara, and I thought that was overkill...

Yeah i have.

I used the 307 brakes on my old 306 and now the 205 racecar.

This should help what i'm talking about with the master:

As the rear piston size has remained the same as you have increased the master size you have decreased the force acting on the rear caliper.

I'm now running my old 1.6 front brakes on the rear of the car with an adjustable bias valve as the 1.6 fronts are a little too strong now so i can dial it back in the wet.

The larger front brakes (both piston and diameter) will create more front bias now also.

The biggest improvement would be to get some good quality pads and higher temp brake fluid.

The braided lines do make the pedal feel nicer.

I'll be looking for some xsi/s16 266mm discs/cailpers later or get some proper 2/4 pot calipers later as the 307 brakes are just silly heavy for the 205. You will also be able to get a better selection of performance pads.
 
I believe the 307 brakes are also used on the GTi180. There are a fair few performance pad options for the 180 if u search overseas.
 
Hmmm not to sure, i know the gti-6 caliper is different than the 307 as it has a bigger piston in it although they are the same size.

I haven't looked at if the 180 is the same as the gti-6 or the 307.

I know Carbone Lorraine do pads for most of the pug range, i'll be giving them a try when i replace the current pads.
 
I've been using Ferodo DS2500, which worked well. I'll be switching to DS3000 or Carbon Lorraine soon for track work. I've found the DS2500 didn't last quite as well as I was hoping as my braking skill and balls (lateness) has improved. 205 is quite a bit lighter too though, so may be fine with the 2500's.
I'm pretty sure the 307 is the same as the 180 for pads.

Well, I went for a blast today and for the first hundred km's, i let them bed in with some short sharp bursts. On the way home from Beaudesert to Canungra there are a few areas that can work the brakes rather well. Without being stupid, i deliberately left the braking a little later than usual and I was very impressed. Great pedal feel and instant response.

I will be heading off to the track soon with a few mates so I can't wait to hammer it through there with them. I just hope now that I can keep up with the car as it's been a while.

I will let you know what track we are going to. Maybe organize a VW V's Peugeot meet and let some Euro's thrash it out for a trophy.

:headbang:

As for the pad selection, yeah I have seen heaps of top stuff for the track but the car wont be on the track all the time as it's my daily driver. That's why I went for the Lucas / TRW. Very minimal warm up and the pure size of the pad will be able to maintain any track work. They are a softer pad so disc wear will also be minimal.

@DRTDVL Your front discs you put on the rear? Do you think it would be the same for the 1.9 discs? The ones I just pulled off the car are 1.9 so I'll be stoiked if I can put them on the rear!

Happy new year to all.

If its QR you are off to..... be very careful of corner one in a 205 Mark.:D

My 2c re the 307 brakes........IMHO i would have just gone some top pads like Endless or Pagid and be done with it. The 307's plus the speedlines add up to approx 15/16 kg in unsprung weight each corner.
If you get serious at the track [and i'm sure you will as its a hoot ] you will wish for less unsprung.

Happy New Year to ya too !! :}
 
I've used Endless pads with the 307 brakes on a 205, and it's just too much for the road. Whilst the combo gives staggering braking performance, the dust and the noise will spoil the experience very quickly. I ended up just fitting Greenstuff in order to keep the dust down.
 
My line was....Endless pads...and standard brakes {not Endless and 307}
Sorry for any confusion.
