    Get your wheel balance checked

    If not could be your brakes

    Thanks for that....... Im going in service this thursday anyway so get them check it out

    If it's only under braking then the disks are warped and need machining or replacing.

    it could be just cementide or non-uniform brake pad deposits on the rotor.

    30780Y,

    Is your car an auto?

    My guess is that it is an auto - in automatics you do tend to brake alot more than in a manual. You also hold the brakes on hard when stopped in an auto, to stop the car moving forwards when in drive. Cconsequently the possibility of warping the front rotors is very much higher than in a manual, where you'd tend to either barely hold the brakes on, or put the hand brake on.

    My guess is the rotors will need to be machined and/or replaced to resolve it.

    Derek.

    unless the rotors are damaged its not a warrantly job unfortunately.

    Brake pads can leave deposits on the rotors in some circumstances as XsaraVTS mentioned. This will lead to a pulsating pedal at slow speed (light application will cause the brake pedal to move as you are rolling down the hill) and will feel like a shaking sensation at higher speeds.



    If you do a search for 306 brakes/pads there are already few opinions on it.

    Sorry, you're wrong. The 307 is NOT semi automatic. It has the Peugeot AL4 which is a true automatic gearbox with a hydraulic torque converter. It is "intelligent" in that it selects from a variety of predefined change-points and torque converter lock/unlock settings to give it better abilities and driving characteristics than many other automatics.

    A "semi automatic" would be a Citroen C3 Sensodrive, a Citroen C2 VTR, a Citroen C3 Pluriel or Peugeot's upcoming Peugeot 1007 which comes with the Sensodrive clutchless manual gearbox.

    It won't be covered under warranty... I don't think. If you've warped them in 11 000km, I think you might need to look at your driving style - it sounds like you brake *really* hard up to say a set of traffic lights, and then leave your foot jammed hard on the brake pedal. This means that the disc rotors are heated, and then cool at a different rate where the pad is held firmly against the rotor, causing the warping. Consider using the handbrake when at a standstill and/or brake hard on initial application, feathering your brake application to virtualy nothing as you stop. This has two benefits: it means your brakes don't get as hot (and get to cool down as you feather your braking pressure) and it stops your passengers heads from bobbing as you come to a standstill with the nose of the car in a downward attitude.

    ICIC so is similar to the A-Class???
    i think that is semi auto too with a cluchless gearbox

    Umm...... I don't brake hard
    Usually i put it on 2nd gear to slow down on the tiptronic
    Is it called Engine breaking (im not really sure what u call it in english)
    But i always wash my car when the brake may still be HOT
    and as i bucket water on the wheels
    i can c lot of steam sometimes
    WIll that be the problem???

    Yes hot metal and cold water dont go well together hence the steam you see,

    Could be the factor why your rotors are warped

    Nope, sorry wrong again. The A class is a clutchless manual. there's nothing automatic about this transmission...just the clutch.

    The auto box in the A class has tiptronic and that's just a regular auto with a tiptronic mechanism on it.

    As GTI124 said, you were wrong again sorry.

    You've hit the nail on the head, and probably learnt the expensive way. Never wash a car just after driving it - you'll very easily warp the brake rotors. No different to taking a glass from the fridge or freezer and putting it under hot water really - things break/twist/crack when the temperature changes rapidly.

    O Sh*t!!! That must be the problem then...... Never do that again
    Thanks 4 that !!!
    How much will it cost me to fix it?
    DeKa u seems uknow quite a lot......... i'll ask u more in the future
    hope u don't mind.......haha

    See what the dealer says, if they are warped, then check out what DBA (disc brakes australia) have for the 307, rather than taking the OEM rotors from Peugeot. You'll save a heap.

    Driving through puddles can have the same effect especially on the L/S of a car cause the water usually travels to the gutter. Can't tell you how many times my rotors have warped on the l/s b/c of this.

    Sometime the vibration can be caused by split CV boots and consequently the CV's start to bind up. Especially noticable when breaking and turning at the same time.

    I got new pair of front rotors for my 405 (cause they were getting tired) for $150 off our Pug club mechanic. Genuine Bendix, not that imitation crap that comes out of Taiwan!!

    Does the 307 have ABS ? This could also be the problem. When braking at high speeds the ABS kicks into overtime and sometimes makes the car shudder with it clamping and letting go of the rotors. My

    surely there wouldnt be a need for replacing the essentially new rotors (11,000kms). the amount of vibration that we are discussing is a 10/20um or 0.02millimeter. And there should be plenty of meat left to machine off.

    ok. not sure on the thickness of the 307 rotor. the 306 wasn't the easiest thing to machine...

    The 307 has the same brake rotors as the 206 GTi 180.

    I had a similar problem with my old 206 GTI. It turned out that the brake pads were glazing up. The cause of this was, I only ever used the brakes gently as I down shifted, rather than braking.

    Peugeot sanded them down with some wet'n'dry and all was good. I was told to use the brakes more solidly. The car was fine after that, I still braked gently, but gave the car a little 'trash' ever now an then so the brakes would be used well.

    Just got back my car from the SERVICE Dept..........
    They said my brakes are warped or something
    Changed new brake disc under warrenty
    But as i received my car
    One of the service guy there came to me and said
    My aftermarket RAZO pedal are too close together and he said as he drive my car
    he is touching the brakes and Accel pedal together
    so he said that might be the problem!!!
    Told me next time if it happens again, doubt will be under warrenty because of my RAZO pedals

    PS: Im quite happy with the job they did on it this time (for once)

    Also saw a blue 180 there
    that 180 just got BADGED by some1
    so he is waiting for his new BADGE i think

    Im quite happy with the job they did on it this time (for once)
