Audi A6 2008 one pad wearing quickly at rear

Good thanks again for all the advice.

The torx head bolts that snapped were a PITA I heated them and tried an extractor but it wouldn't work - in the end I drilled them out and although I was a bit off centre with my drilling the remaining bolt disintegrated and I was able to run 2 new 25mm m6 cap head bolts in.

I spent a long time cleaning the caliper and filing the outer surface that would contact the piston boot, the caliper is pretty rusty I would love to have given it a blast in a cabinet but this tends to bring more issues than good!

I've never replaced a boot and piston before it went ok i liberally applied rubber grease to most surfaces and ensured everything was very very clean before starting, this was tricky due to rust specs but i'm pretty happy.

Car parts for less have some good discount codes just now discs, pads, air filter, wipers, pollen, fluids, cleaners, fuel filter were £180. The Frentech piston kit was £22 odd.
Very annoyingly even though I double checked the spec (mine is 1kd solid discs) the supplier gave me the wrong guide pin / sliders so I just cleaned up the old ones they were actually fine inc the boots.

Have attached the pics below!

Thats good to hear.

My calipers dont look as rusty as yours, i expect to have similar issues though.

I will be plus gassing the motor bolts via the small hole each day until saturday.

One thing I know for sure is cheap cheap car washes that use strong wheel cleaner / traffic film remover away from them that really speeds up rusting!

I utilised that hole and drilled it out to run a longer bolt through.

I managed to snap / break the small securing lug on the epb to caliper wiring plug it still goes on but need to secure it with something I think!

A cable tie around the motor should hold on the plug.

Great thread

How much is it for a whole new caliper with electrics & how much have you guys saved ?

[dan2485]

A new caliper from the dealer £300 or a refurbed one plus returning the old one around £100.

If the motor goes they can be got for around £60 on Ebay.

ok thanks

That's not bad for the dealer ecp or car parts for less were about £250 if you give over your old calliper. That was for trw as well.
ill happily go that route eventually knowing that at least I gave this a bash!
