MG MGB Technical - Brake Caliper Repair

Last year I ruined my master cylinder not understanding its construction. So now I’m trying to repair the calipers on my front disk brakes more carefully. The Moss repair kits (180-981)include three parts. I have removed the 2 rubber “O” rings but how does retainer come out? Do I need to replace it or can I just fit the inner seal and dust seal back in? If the dust seal retainer must be replaced how much pressure can I use to “prise” it out according to the Haynes Repair Manual?” Could I apply heat to loosen the retainer?

Thank you

Hello anny,

The retainer, you have to pry it out with a screwdriver. To help just cut it. To settle the new one in place, a piece of hard wood with a small hammer will do the job. You must be carefull and be gentle. One important item is to replace pistons if they are pitted.

Cheers,

Try to get it out in one piece if you can as you may have to reuse it if the new ones are really stubborn.

thank you for this information... but can I just stuff the seals back in the slots and avoid using the retainer part of the repair kit?
