What is the purpose of a piston seal in a brake caliper?

The piston seal in a brake caliper serves two main functions. It helps to prevent brake fluid from leaking out of the caliper and also keeps dirt and debris from entering the caliper bore, which could damage the piston or bore.

How do I know if I need to replace my caliper piston seal?

You might need to replace a piston seal if you notice brake fluid leaks around the caliper, or if you are performing a caliper rebuild. Worn seals can also contribute to a spongy brake pedal feel.

Does this seal come with any other hardware?

This product is a single 34mm piston seal. It does not include any other hardware, such as dust boots or O-rings, which would typically be purchased separately if needed for a caliper rebuild.
