Brakemaster cylinder
Repair kit
For Brembo brake cylinder rear wheel with 15.87 mm diameter.

Repairing instead of replacing is the motto of this clever repair solution for the master cylinder of the two-valve Boxer: The complete "inner workings" are replaced in just one step and the brake is tight, smooth-running and safe again.

The lubricant is for resealing the caliper seals.

ATTENTION:
Only for repair in a specialist workshop!

Price for set.

For the classic BMW 2-valve Boxer models R 100S, R 100RS, R 100RT until 9/1980 with rear disc brake.
