More R32 Brake Queries

[AzzurrA]

Hi all,

I have a bit of a problem with my R32 at the moment....

My brakes 'creak' when i'm braking, and you can feel the pedal 'slip' a tad (i.e. less than 1mm) lower with each creak... Is this air in the system?

I had the brakes Bled probably a month? ago, and they used Motul RBF600 Fluid (which is what i already had in there) and they said that they bled all the air out of the system, but that it was bad before they did... and it felt okay. I did a track day they day after they bled them, and the brakes felt fantastic,was able to push 10/10ths into a corner without fear that it was going to randomly lock a wheel unless i was being stupid with the brakes. Well after the bleed/track day, the creak MOSTLY went away, but was still there a bit... anyway, lately the creak is back, and i was giving my brakes a bit of a workout on the way home, as they feel a bit doughy, and every time i used more than about 1/2 the pedal, it would lock the rears and send the ass end of the car to try and meet the front....

Now, to me, this sounds like i've got some big air bubbles in my front lines... i was wondering what everyone elses opinions of the matter are?

The creaking could be a result of some of the pistons being stuck in the caliper. Get the calipers overhauled.

the noise is sticky pistons in the calipers(usally only one is doing it)

peel the dust boot back on the noisy one and carfully push the piston out but not all the way!

get some brake caliper lube(clear liquid used during an overhaul.)

cote it nicly and push it back in and your done.

every third 32 i comply has this noise!

Yep, I had this noise in my '32 for a while - had the front brake calipers overhauled with new seals etc (didn't cost much)

....end result - noise gone!
