How to Change Calipers: Tips for Safe DIY Replacement

May 11, 2025

Changing brake components such as brake pads and calipers can be a straightforward task with the right knowledge and tools. However, sometimes challenges arise, like a stuck piston or sliced rubber boot in the caliper, especially when dealing with a vehicle older in design, like the 1990 Subaru Legacy or a more modern car like the 2012 Honda Accord. Knowing how to change calipers is crucial for efficient brake maintenance and safety.

Recognizing the Need to Change Calipers

Squeaking brakes or brakes that freeze are common indicators that a brake caliper requires attention. It’s vital to inspect for external damage, such as broken rubber boots, or internal issues like a seized piston, which may necessitate replacing the caliper.

How to Change Calipers Properly

Learning how to change calipers can prevent unnecessary visits to the mechanic. Here's a step-by-step guide you can follow:

  • Locate the brake caliper behind your vehicle's tire.
  • Use a screwdriver to remove the caliper along with the brake pads.
  • Unscrew the caliper bracket and disconnect it from the brake hose, disposing of the old caliper carefully.
  • Connect the new caliper to the hose swiftly to avoid brake fluid loss, then reassemble the brake components and return the tire to its position.

Special Considerations for Car Models

While the process remains similar across many vehicles, a 1990 Subaru Legacy might pose different challenges compared to newer models like a 2012 Honda Accord. The Subaru's rear driver's side caliper, for instance, may require more attention due to age-related wear and tear. Meanwhile, in a Honda Accord where the piston is seized, preparing for these scenarios will save time and effort.

Finishing Touch: Bleeding the Brakes

After installing a new brake caliper, the next important step is bleeding the brakes. This process ensures the removal of any air pockets that can cause spongy brakes. Follow the vehicle's specific brake bleeding procedure to maintain brake performance and ensure safety.
