What does a brake wheel cylinder do?

The brake wheel cylinder is a component within your drum brake system. When you apply the brakes, hydraulic pressure from the master cylinder forces the pistons inside the wheel cylinder outward, pushing the brake shoes against the rotating brake drum to slow the vehicle.

What vehicles does this DFC brake wheel cylinder fit?

This wheel cylinder is designed to fit a range of Buick vehicles from 1961 to 1966. This includes models like the Electra, Estate Wagon, Invicta, LeSabre, Riviera, and Wildcat.

Should I replace both sides when servicing drum brakes?

It's generally recommended to replace brake wheel cylinders in pairs (left and right side) for balanced braking performance. If one side is worn or leaking, the other is likely to be in a similar condition.

Product Details

If you're working on the brakes for a classic Buick like an Electra, LeSabre, or Riviera from the early to mid-60s, this brake wheel cylinder is a key part of getting your stopping power back to where it should be. It sits inside your drum brake assembly and is responsible for pushing the brake shoes outward against the drum when you press the pedal, creating the friction needed to slow down.

This wheel cylinder from DFC is built to fit right into the original location on a wide range of Buick models from 1961 through 1966. It's a well-built replacement that helps restore the hydraulic pressure needed for your brakes to function correctly. Replacing these can be a good idea when you're doing a full brake job, especially if you notice any leaks or corrosion on the old unit.
