Re: brake shudder

usally its because the disc rotors are warped. you can get them machined or if they are too thin you have to get new ones. this was my experience anyway.

Re: brake shudder

I dont think its the driver because my mrs drives slower than my granny and she drives a ba fairmont and her car has break shuder. but it may have something to do about braking harder than normal and the car being heavier. It is a ford problem as all people do drive differently and a performance car should handel a performance driver if u know what i mean.

Re: brake shudder

I've just started to get brake shudder in my BA XR and it was on a family trip to Sydney. No heavy braking or anything like that you can pin it to, all perfectly normal country/city driving. Seems to be a problem with a lot of BA's. I thought someone said on the forums that Ford now has a proper fix for it?

Re: brake shudder

The problem is common regardless of driving style and/or model and more than likely is disk thickness variation rather than warpage.

I've had mine machined 3 times in about 13,000k's, on the third machining the dealer installed a shim kit (which is part of the TSB) and so far no further warpage @ 17,000k's.

In my brother-in-law's case, not so. He has the self skimming thing fixed to his brakes after his XR6 went in for brake shudder a second time. Now the shudder is coming back again. It is bloody annoying that Ford can't fix this. I think I will suggest to him that he should get them to put new pads on next time...I am guessing that they would fall under warranty and that he wouldn't have to pay, but I am not sure.

It is unacceptable.

But in answer to your theory bosco, I believe he does drive the car reasonably hard, not speeding off at the lights at every chance he gets and then braking hard at the next lights, but still does take off reasonably quickly.

Re: brake shudder

My car has had a fairly hard 25,000km. Club events and such, and the 18" Dunlop SP9000 are needing replacement.

I've got the standard taxi pack brakes and apart from wear of the pads, the discs are still in very good condition and the braking is still quite adequate. When I replace the pads soon, i'm guessing that braking will come back to near new condition.

The biggest problem with track days is that the BA falcon weighs sooo damn much and repeated laps stopping from around 200km/h is not something that the standard or even premium brake system were designed for. Perhaps the Brembos on the GT would fair better, but you just can't think that a 1800kg car is suitable for track work.

45,000km service coming up - and i'll be asking for a sizable list of fixes:
* Gearbox (3rd time)
* Steering click (5th time)
* Brake Shudder (2nd time, and has the applied "Fix")
* etc...

Re: brake shudder

Oh, and just so you know, my bro-in-law hasn't been to any track days at all, so he doesn't fit into that criteria.
