Bolster 0 Posted December 2, 2003 Scenario - I get brake judder when the brakes are warm. I have narrowed it down to the drivers front disk as it has a sqeak when the brakes are not on and there is much more brake dust on that wheel. There is no judder when slowing down with the handbrake. The disks are fairly recent (last 8 months). I am also hoping it is caused by the new disk going onto a dirty hub (mentioned in another link). I have read on the forum that a warped disk is caused by a change in the disk when it gets hotspotted. A mate of mine can skim the disks for me for nicks Question 1: Is skimming the disks likely to cure a warped disk? Question 2: Do I have to skim disks as a pair if the FNS is OK?

stevemac 0 Posted December 2, 2003 With all due respect, it will be very easy for opinions to be offered etc, on-line. However brakes are a very important safety feature of a car & I would advise you to have the car checked out & road tested by a suitably qualified person. Squeaking when the brakes are not applied could well be a faulty/loose wheel bearing. The answers to your questions are 1. Depends how bad the damage is & how worn the disks are. 2. I have always skimmed disks as pairs. Quote Share this post Link to post Share on other sites
Storm 0 Posted December 2, 2003 Disks are dirt cheap from GSF & Eurocar parts. Not worth skimming. Quote Share this post Link to post Share on other sites
h100vw 0 Posted December 2, 2003 VR6-er, agreed. Defo not worth the effort. Take them off, skim, refit. Still judders, off to GSF for new ones! Could also be a partially seized caliper. The pads rubbing may have overheated the disk and warped it. Looose wheel bearings sometimes give you an intermittent bad/long pedal, as the pads sometimes knock the piston back further than normal.

Scott 0 Posted December 2, 2003 Yeah agreed - wouldnt bother with hassles of skimming unless expensive discs...... GSF did me Pagid drilled discs and pads for front for 100 notes all in. Quote Share this post Link to post Share on other sites
Riki 0 Posted December 2, 2003 I would check the slide pins in the calipers to see if they are free. If you are not used to working on brakes get someone to check it for you. The heat of the calipers causes the paste to dry out and if the boots have been torn when someone has fitted pads carelessly water can get in causing the pins to seize. it will then brake unevenly. Could be you cause? Might be worth a look. Quote Share this post Link to post Share on other sites
Bolster 0 Posted December 2, 2003 Yep - seems to be the consensus - I'll be trying the skim (after all it is free) then I'll be paying a visit to GSF (just down the road). The bearing is also getting replaced as I'm sure it's nearly toast. Are the bearings (I'll be doing fronts and rears shortly) a GSF or stealer only part?

stevemac 0 Posted December 3, 2003 I would use original VAG bearings. I've gone through 2 sets of GSF rear bearings in 7 months !! (I doubt their fronts would be any better) Quote Share this post Link to post Share on other sites
