Review on Bicycle Hydraulic Maintenance XTRM9020 Calipers by David Barit

Revainrating 5 out of 5

Excellent especially during a parts shortage

I used them off label to replace a broken ceramic piston in a BR RS505. Flat ring and piston fit perfectly. The caliper fluid port o-ring is too small for the 505, but the outer rubber washer fits the bolt.

Pros
  • AUTOMOTIVE SHOP HIGH TEMPERATURE AND HEAT INSULATION (750 degrees Fahrenheit maximum operating temperature) NOT CRACKED OR CRACKED They include all required gaskets and o-rings as shown in the pictures.
Cons
  • Out of fashion
