Good advice Charlie, hadn't thought of good old heat. Any tips for rebuilding these old calipers?
Yep, buy new calipers from MG Cycles.
But, Jim says he wants to stick with the dual-bleeder calipers.
Doh! I didn't read the last bits of the post.What's the advantage of dual bleeders?
Does the S3 have linked brakes? I'd think not, and this might preclude using hoses from T3 and later..Peter
I bought a pair of new Brembo calipers for my Eldorado but wanted to try and preserve the original ones for my 750S3 and 750S clone. The original bikes used dual bleeder Brembo calipers to keep the S3 original and if they worked out then do the same on the 750S bike.The other thing I noticed on the S3 that is different from the 850T is the S3 has steel lines from the front calipers then rubber hoses, the 850T has rubber hoses direct to the caliper. This is a picture of the 850T front caliper and hosesAnyone know what other Guzzi would use the same rubber hoses as the 750 S3?
Speigler (and others like Earl's) can make to order just about hose that you want. So unless you gotta' have original style rubber hoses, sourcing them isn't really a problem.
I always use grease to remove stuck pistons now. I saw a piston fly across the workshop using compressed air a few years ago, could do all sorts of damage to man or machine :-\
A shop rag wrapped around the caliper half will catch the piston. Never had one fly anywhere...
