I just took the B out for a quick check after some exhaust clamp tightening and my brake pedal went slowly to the floor. Back in garage I see Brake fluid around the outside of right fronttire. Checking the lines at the wheel can't see leaks at the connections, not a good thing. As the boss presses her foot to the floor, fluid starts dripping from the bottom of the brake housing, it seems that an inner seal has let go. At IMHO, any other ideas? I was really hoping I would be working on it rather than driving it on the fourth, NOT. May need to add to that order Tony!
Is it even financially logical to repair the seals etc or should I just replace the caliper assy?
Thanks,
Mike
 
The calipers are actually pretty easy to rebuild. The cost is not that bad when compared to new calipers. The only suggestion I would have is to split the caliper halves, even though the manual tells you not to do that. It makes pulling the pistons, and cleaning things up much easier. You just have to remember to order the special o-ring that goes in between the halves, as they are not included in the kit.

I would also opt for the stainless pistons, as they will last longer than the chrome ones. I just rebuilt my calipers, and it was a breeze after I split the halves. Years ago, I rebuilt them without splitting them, and it was not a good experience.
 
If you split the calipers buy bolts and torque them to the proper torque. Don't forget to do it in a clean area and your hands should be clean or use latex gloves.

I forgot to tell you Moss motors dosn't recomend splitting the calipers and dosn't sell the 'O'ring or the bolts. I think that I bought mine from Brit-Tech or BritVic.

The bolts should not be a problem, but the Moss part number for the square o-ring is 180-285, they call it a fluid channel seal.

Bob at Brit-Tek has nitride coated pistons. They are a bit of an expense, but when working on the brakes, cost should not be a primary concern.

No matter how fast you go, you have to be able to stop.
 
In the interest of safety and 'cause I know my limitations, I'm just replacing the caliper assembly. As Ron points out, cost is not a primary concern on my brakes. Thanks all for the suggestions, I've tackled pretty much everything so far myself with the forum's invaluable help. but the brakes are something else. Safety Fast---Stopping Fast!
Happy Fourth of July

Thank You Vets.
 
Rebuilt units are the way to go if you are not comfortable with rebuilding them. Let us know how things work out.
