I don't know if anyone can help with this, but here goes.
Ever since I had my front calipers 'refurbished' I have brake problems. When I first get them back from the garage (A4 Audi), they're fine. Smooth as silk. But after about 3,000 miles, they start to judder. Back to the garage for new pads (and discs last time) and they're fine again....for about 3,000 miles! They've just started to judder again for the third time, 3,000 miles after the last set of new pads and discs. The first pads were Pagid, but the last ones weren't (but don't know what brand they are). Now, A4 Audi tell me this: "the calipers were 'over sandblasted' and the pads are loose in the calipers. Once they pads 'bed in', then they move in the caliper and hence the shuddering". To me, this sounds unlikely and I can't get my head around a) how sandblasting could really have such an impact on the calipers and b) how the brakes can perfect for as long as 3,000 miles (seems like a heck of a distance for bedding in) and then start to shudder. Anyone have any idea what's going on? ![]()

Sand blasting will remove some of the calipers but not enough to cause the pads to judder.
Can you feel it through the pedals or the car? Are you a stamp on the breaks style of breaker?

I can feel the judder (and see it) through the steeing wheel and feel it on the pedal.
I'm usually a very gentle braker, but I have tried a few heavy foot sessions on the business park where I work, and it brings the car to a rapid halt no bother. However, on a couple of occasions there was a short skid and I didn't feel the ABS kick in. Relevant? The judder is worst, I think, from/at speeds of around 30mph and when the brakes are hot. One thing I'm wondering is that they might not have replaced the tension spring. I'll have a look at the weekend. Would that cause these symptoms?

Could be discs but they replaced them?
Twice? Could put some copper slip on the runners for the pads and back of the pads. see if that helps if they are saying its the pads. I'm trying to think what else it could be. I assume he'd know what warped discs feel like?
