Review on Dorman M544 Brake Master Cylinder by Richard Summerall

Revainrating 3 out of 5

The cover leaks through six screw holes.

The cover bolts penetrate the brake fluid chamber, allowing brake fluid to flow around the bolts. The screws are 1/4 inch and have only one lock washer. There is no sealing washer to prevent brake fluid leakage through the threads. Brake Fluid Chamber A sealing washer must be used to secure the cap to prevent leakage of brake fluid through the threads into and out of the cap Critical part with a major failure.

Pros
  • Reservoirs, caps and liquid sensors are included in most units
Cons
  • There are other interesting options.
