Vibrating when braking

[sonny]

Use a bradle or a metal rod. No cleaning spray really required, just a bit of elbow grease.

I use my jet wash, comes out easy.

Audi changed my discs out FOC after only 5 months of fitting as they were warped again ~ that was in April 2011.

I'm getting the same sensation again..... in a couple of weeks I'm going to go back to Audi about them. Think they should offer ceramics (FOC) to me.

I drove an RS4 saloon for 2.5 years with no problem. This avant I've had for a year and a half and this will be the 3rd set of discs the car requires.

My driving style hasn't changed so think they are manufacturing problems with the discs.

Maybe need to look out my knitting needle and give the holes a proper clean at the weekend.

Funny as I have never had a problem with my discs and I hammer them esp on track days.

People have commented they need working just like the engine needs a good blast now and then.

Thats why

They are performance pads and discs well overspecc'd for day to day driving. give them a real blast on track and it'll keep them happy.

There comes a time though that when this problem occurs and then you try and cook them a little that it does not resolve the issue, almost like going past the point of no return. Then skimming comes in handy.

I think I need a euromillons win. That way I can build a track in my garden so I can keep my brakes in tip top condition

Well the braking technique has worked a treat. The holes are caked though, so when I give her a clean I will clear them out. Good as new then I hope

Yeah, the pad transfer deposits can build up tothem point where they start to turn solid and are as tough as the disc. Apparently still possible to wear down with the brakes but it takes a long time and quicker/easier to skim.

That's good news. It's something you want to repeat regularly like an Italian tune.
Also for light deceleration its better to use the gears. Not only saves your brakes from building up again but it good fun blipping the throttle to downshift (ESP with a miltek)

I actually had a fellow rs4 owner come up to me in the car park asking how much it was to fit the sequential paddle shift in the car 'cause of the downchanges.
