Dorman - First Stop Drum Brake Wheel Cylinder Kit P/N:3644
Service a worn drum brake wheel cylinder with the Dorman - First Stop Drum Brake Wheel Cylinder Repair Kit, part number 35627. Its components are designed to match the original parts required to repair the cylinder. It fits many vehicles, among them the 1992-2002 Chevrolet S10, 1992-2002 GMC Sonoma and 1994-1995 Chevrolet LLV; see the Buyer's Guide tab for the full list. The catalog lists it for the rear left and rear right wheel cylinders.
The wheel cylinder is mounted inside the drum brake assembly. It uses hydraulic pressure from the master cylinder to push the brake shoes outward against the drum. When its internal components wear, this kit supplies replacements so the cylinder can be rebuilt rather than replaced as a complete unit.
Follow the vehicle service information for the rebuild procedure, and bleed the brake hydraulic system once the work is complete.
