Brembo Rebuild

[Richie K]

So, I couldn't wait till next week, I've brought my Brembo's into work and have one of the lads helping me. :innocent: Having looked at the calipers, I want to know which way I should have them ie. Bleed nipples to the top or bottom of the caliper, Larger piston to the top or bottom or does it matter which way round the pistons are ?? I can't take any pics till I get home from work, so I hope you understand what I'm trying to get at:thumbup1:

 

Funkysi, you around??:whistling:

one thing I would say and I have been told many times with people in the know. is don't split them apart.

Bleed nipples to the top!!

 

Regarding splitting them, it shouldn't be a bad thing as long as you have new rubber O-rings for where the fluid galleries join between the two halves. If you don't have those, I'd keep them together.

 

That said, I think I'll be keeping mine together anyway when I get around to refurbing them :thumbup1:

I split mine although not brembos and never had any issues, brakes were perfect after I rebuilt the stock callipers.

 

But at your own risk of course. :)

Allthough this is for AP calipers the information you requested is the same. Leading caliper configuration - larger bore at bottom. Nipples up.

Personally, I wouldn't split calipers unless absolutely necessary.

Thanks for that Andrew:thumbup: Well it looks as if I'm going to have to split these freshly powdercoated calipers, because, Guess What?? Some Ape has put them back together the wrong way already!!!:cursing: I was trying to work it out off Andrews Diagram and have just copped that I have a small piston lined up with a large piston!! So these have been split and put back ARSEWAYS!! I've two choices now, Get the old set (Donor set) powdercoated and rebuild them as they've not been split or split the newly powdercoated ones and switch around the sides changing the o rings also.:thumbdown:

[AndrewG]

If you do decide to split the powder coated ones the split line would not normally be visable once the calipers are mounted and

wheels back on. The main reason I mentioned not splitting calipers was based on my knowledge of AP calipers which have

the caliper bolts thread locked and can be difficult to remove without damaging the threads. This may not apply to the Brembos.

I didn't get mine split. Have heard of horror stories regarding stripped threads and poor re-sealing etc. You can't see that part of the caliper too well and provided you make sure the calipers are totally clean before rebuilding, they'll be absolutely fine. Mine were washed by the powdercoater after I'd had them back and then I went through them with an airline.

[Richie K]

Well we're sitting in my office having split the calipers, I wish I could take a pic of them, they're spotlessly clean! The powdercoaters obviously treated them with something as the bare metal centre's are so smooth and clean. There's no seals as such between the two halves and it makes putting the new seals and pistons in exceptionally easy:thumbup1:

The bolts took a sharp jolt to break loose but there appears to be no threadlock on them. Have the first one rebuilt, but won't be able to give a final analysis until they're on the car:thumbup: FINGERS CROSSED:thumbup:
