Rear caliper rebuild - '90 200qa

[Konstantin Bogach]

You will have to remove piston from the caliper. It means you need to detach brake line (or pinch it if it is possible in general).  I would recommend to take the caliper to the bench.  After you remove the piston you need to stretch new boot onto the piston lower end, place the boot's lower lip into the calipers groove, screw the piston into the caliper(piston should be lubbed as the boot must not rotate with the piston), position the upper lip in the piston's groove. Reinstall caliper.

The caliper works fine, but the boot over the piston ripped.  Would it be 
possible to replace the boot by stretching a new one over the piston and 
seating it in the caliper?  If not, I'll have to get another rebuilt as I 
don't have time to rebuild it.
