What does a brake wheel cylinder do?

The wheel cylinder is part of your drum brake system. When you press the brake pedal, hydraulic fluid pushes pistons inside the cylinder outward. These pistons then force the brake shoes against the inside of the brake drum, creating friction to slow or stop your vehicle.

How do I know if my wheel cylinder needs replacing?

Common signs include a spongy brake pedal, brake fluid leaks around the rear wheels, or the rear brakes not applying effectively. If you notice any of these symptoms, it's a good idea to inspect your wheel cylinders.

Does this wheel cylinder come with hardware?

This part is the wheel cylinder itself. You will need to reuse your existing hardware or purchase it separately. It is recommended to inspect your brake shoes and drum hardware when replacing the wheel cylinder.

Product Details

When you're working on the rear brakes of your 1977-1983 BMW 320i and need to replace a worn-out wheel cylinder, this part from DFC is a solid option. The wheel cylinder is a key component in your drum brake system; it uses hydraulic pressure from the master cylinder to push the brake shoes outward against the brake drum, slowing your car down. If yours is leaking fluid or the pistons are seized, your rear brakes won't work correctly, and that's a safety issue you don't want to ignore.

This wheel cylinder is built to fit your specific BMW 320i model, meaning it should install without needing any modifications. It's designed to handle the hydraulic pressure needed to engage your rear drum brakes effectively. Replacing a faulty wheel cylinder is a common part of a rear brake job, especially on older vehicles where seals can degrade over time.

Make sure to check your brake fluid level after installation and bleed the brake system to ensure proper operation. This part is sold individually, so be sure to order two if you're replacing both sides.
