Took my bads off a little while back and noticed my pistons looked like this.








I'm due for a brake job so I want to take care of this at the same time. Are they just rubber seals? And if so where can I get some replacements?

 

anybody?

 

Those are the dust boots. BUT, of you melted the dust boots, then the seals being 1/4" away need to be replaced.

It's really easy to rebuild calipers, just make sure you get assembly lube for the pistons and seals.

Thanks for the info. Where can I get the stuff to do this, would the dealer have it?

 

nvm just saw your link to czp. Went ahead and placed an order for them.

 

Was that just from Ok heat, or were you having some high speed fun??

 

BTW:

The pistons are plated, so don't use sandpaper on them.
A Mr Clean Eraser Sponge, or whatever they call it, with a little Bon Ami, will clean them.
Pushing the pistons back in: Make sure they are lubed, if no lube use brake fluid. They will want to ****, and bind in the bore, a slight rocking motion as you push them down with your thumbs will help.

Edit: SEE OHH SEE KAY is not a bad word.

Like **** you gun before firing.
**** fighting is illegal.

 

Thanks for the tips. Just got my new pads and seal kit in today for czp. Major props to them and their customer support.

I have done some pretty good tracking that has been quite demanding on the brakes. Hitting 100+ on straights and 60-70 in corners.

I'm probably going to start on the install tonight or tomorrow. I'll let you know if I run into any problems.

 

Wake, to be honest, the rebuild is nice, but probably not necessary.

I've been tracking without dust boots for quite a while (with tons of dusts, offs, blah blah) with nary an issue. Virtually everyone else I know tracks under the same conditions.

The first time you expose the boots to track conditions, they'll be destroyed anyways.

 

Hmm interesting. Well none the less I'm about 40k miles now so I'm sure it won't hurt. Plus my brakes just haven't been feeling very good lately so I'm sure anything can help. Might as well do it all while I'm down there. I'll be sure to post back with how it turns out.

 

Ok so I've got the caliper off the car and put the air hose up to it to pop the pistons out, but only one of the 4 came out. How can I get the other 3 out, other than just using some pliers?

 

Oh, did you not put a pad between the pistons to limit their travel??

The compressed air is used to just free the pistons, not pop them all the way out. They are supposed to go part way out, then use you fingers to do the rest of the way.

Put the piston back in, insert one brake pad between the pistons, then try the air again. All four should still be within the seal coverage.

If Mike jumps in with his needless comments again, then Im out of here.

 

BTW, anytime I track ANY car or bike, I go with a completely new brake setup.

 

I tried putting something in between them to limit how far they go but still just get one or 2 at a time. I call up a tire shop to see if they had a bigger compressor to try it on so I'll run down there if I cant get it.

 

Ok got everythig apart and all cleane up. Now putting them back together. The kit came with 2 things of grease. On for the seal and one for the boot. But it didn't say which is which. One is a light red and more runny the other is a dark red and is almost like a paste. Anyone know which is for which.
