Rebuild the internal sealing of your brake master cylinder instead of guessing at loose parts with the Dorman - First Stop Brake Master Cylinder Repair Kit TM3626. This kit supplies parts and hardware designed to match the originals needed to service the master cylinder, and it drops in as a direct-fit repair for a wide range of vintage Buicks — including the 1937-1942 Century Series 60, the 1937-1942 Limited Series 90, the 1940-1942 Roadmaster Series 70, the 1950-1955 Special, and the 1957 Super (see the Buyer's Guide tab for the full list of applications).
If worn internal seals are the cause of a sinking pedal or fluid bypassing inside the cylinder, this kit replaces those components so the master cylinder can hold and move brake fluid as designed. Backed by Dorman's US-based product experts. Country of origin: Taiwan.
