Brembo caliper bolt?
Hi all,
In the process of rebuilding calipers, of course one of the caliper bolt was seized. Anyone know where to source a replacement? Looking for the bolt circled in red. Last edited by Sam!; 11-30-2021 at 04:15 PM.. |

Post a picture of one of the bolts you removed. It appears to be an external torx head bolt, which are rare but not impossible to find. If that's the only thing about it that's out of the ordinary you can probably substitute a bolt with the correct length and threads with a different head if you can't find external torx head.

The rebuild kit actually include replacement o-ring for crossover, no way of exchanging without taking apart the caliper. |

It's a brake rotor, not a GE90-115B. I can't see more than a Class 10.9 (that's how metric bolts are graded) bolt being required, especially as it's only one of four. It may not be possible to get an exact match, but it shouldn't be that difficult to find a bolt that will work.

Utilize a thread gauge to determine what thread is required for a replacement bolt. Yes totally fine splitting calipers as alot of rebuild kits come with internal O-ring that requires removal of bolts to change out. Strip the old coating off via sand blaster ensure all the holes internally to caliper are protected. No need for acid stripping Coat each caliper halve with desired coating. I always polish my pistons with 2000 and 3000 grit on a drill press with a diy holder I made up. Rebuild seals and Reassemble using medium loctite or red loctite if you never plan on redoing them again. If you did not coat the new bolt heads a good rust Corrosion method is to Black oxide treat them or Paint the bolt heads after you assembled the rotor. just my 0.02 |
