Do Locked Brakes = Rebuilding The Calipers

Postby rowejimf » Thu Feb 09, 2012 5:56 pm



I pulled the 77 Cafe out to do a title transfer inspection today. Luckily I only had to take it it around the corner. Made it to the Chevy dealer and the front brakes were smoking. They actually locked up. Question is, will this necessarily require a front caliper rebuild as outlined by Wingman in his awesome "how to" instruction? Also how much does the 82 brakes differ from the 77?

Thanks guys....

The GL1000 brakes are not all that different from GL1100 brakes, there are less pistons in some case, but the underlying principle is the same.

There are normally three causes of locked-up brakes:

- Seized slider pins
- Seized piston
- Blocked return port in master cylinder

Of the three, the third is the most common.

The easiest way to tell is to loosen the brake line fitting at the caliper to allow brake fluid to escape. If the brakes free up, then the problem is the blocked return port. If not, then it's either seized slider pins or pistons, and it will be fairly apparent which one of them it is once you start removing the caliper.

Great post WingAdmin. The calipers do have different spacing from the boss to the rotor, and the mounting to the fork lower is different too. So I do not think you can put on '82 calipers without some modification. But it certainly can be done from what I understand.

Thanks Wingman and Fred. I ordered rebuild kits for the master and calipers. Not actually putting a different set of brakes on the 77. I appreciate the fantastic advice that you guys provide.

Thanks,

Jim
