HOW TO: Brembo Caliper Breakdown

[doctorres112]

First I want to start out by saying thanks to Martin from Girodisc.com for all his help. I had lots of questions and if it wasn't for him I would still be messing with this.

Second, I am not responsible if you mess something up by using this how-to on your project.

The purpose of this how-to is take out the caliper pistons and dustboots if you want to re-poweder coat your brembo's. This may also be a good idea if you aren't sure what condition your dustboots/seals are in since you probably bought the calipers used. You can buy the rebuild kits for $150. That's $50 a piece for the fronts and $25 a piece for the rears. I bought these kits from Martin at Girodisc.com. I would call them and let them know what you are doing as they have recently been made aware of us eclipse guys performing the evo brembo swap. All in all it's a fairly easy job and pretty straight foward. This is my first "how-to" so be kind and let me know if something doesn't make sense.

TOOLS NEEDED:
3-4 different flat head screwdrivers
a cut down piece of 2x4 or some small pieces of 1/2 ply-wood (acting as a shim)
air compressor w/air gun attatchment
beverage of your choice


STEP 1: Remove brake line bolt from back of calipers and ensure you get as much of the residual brake fluid out.



STEP 2: Place your shim where your brake pads would sit. You will know the shims are in place because the pistons will have about a 1/4-1/2 inch if space between them and the shim. Once they are in, use your air gun and blast air where the brake line bolt was that you removed earlier.



NOTE: While performing this step, it's important to know that all the pistons must come out from their hole together. By that I mean that if one piston is removed completely the others won't come out because the forced air will come out freely from that empty piston hole and will not create any pressure for the rest of the pistons. If that happens just put it back into the hole and push it back in place and try again. Ensuring your shims are in the right place will make this easier.

**This is how it looks if your shims are placed incorrectly


**This is how you push the piston back in place


If you can't push the piston back in go ahead and remove the dustboot as that should make it easier to get it back in.


STEP 3: Once you got it figured out and all the piston are emerging together it's time to take them out. I am sure there is a better tool for this but I used 2 flat head screw drivers and gently lifted out the pistons. You have to be careful not to damage the pistons so take your time, The forced air has done most of the work already.

This is how it should look with all pistons emerging together



This is how to remove the pistons




STEP 4: Once all the pistons are removed you can remove the rest of the dustboots.





STEP 5: After the dustboots are out, you need to remove the seal gaskets. I used an eyeglass screw driver. It is really small and great for getting in there and lifting out the seals.





And finally, it should all look like this



If anyone has any questions don't hesitate to ask. I hope this helps

Thanks,
Chris

awesome write up, i think i may need to rebuild my rears

[doctorres112]

The rebuild kits for the rears are $50 ($25 ea.) from Martin @ Girodisc.com
Good luck and let me know if you need any help
