The brake caliper piston is a critical component of your vehicle's braking system. If the piston becomes stuck, it can cause a variety of problems, such as decreased braking performance, decreased fuel efficiency, and increased brake wear. Fortunately, freeing a stuck brake caliper piston is a relatively easy task that can be completed in a few simple steps.
Tools Needed to Free a Stuck Brake Caliper Piston
Before attempting to free a stuck brake caliper piston, it is important to ensure that you have the right tools for the job. The tools needed for this task include:
- A C-clamp or large flathead screwdriver
- A brake caliper piston tool
- Brake fluid
- A rag or shop cloth
Steps to Free a Stuck Brake Caliper Piston
Step 1: Unscrew the Brake Caliper Piston Retainer
The first step in freeing a stuck brake caliper piston is to remove the retainer that holds the piston in place. This is typically done by unscrewing the retainer with a flathead screwdriver or a C-clamp. Once the retainer has been removed, you should be able to pull the piston out of the caliper.
Step 2: Clean the Piston
Once the piston has been removed from the caliper, you should use a shop cloth or rag to clean off any dirt and debris that may be stuck to the piston. This will help ensure that the piston moves freely when it is re-installed in the caliper.
Step 3: Lubricate the Piston
Next, you should use a brake caliper piston tool to lubricate the piston. This is done by inserting the tool into the piston and applying a small amount of brake fluid. This will help ensure that the piston moves freely when it is re-installed in the caliper.
Step 4: Re-Install the Piston
Once the piston has been cleaned and lubricated, it is time to re-install the piston in the caliper. This is done by inserting the piston into the caliper and then screwing the retainer back into place. Once the retainer has been securely tightened, the piston should move freely when the brake pedal is depressed.
