How to Inspect Car Brake Calipers

Brake calipers are a hydro mechanical energy conversion device, also known as an integral part of your braking system and should be checked any time your brakes are serviced. They should also be checked every six months or according to the time frame in your vehicle's maintenance manual.

Difficulty: Easy

Instructions

1. Locate the brake calipers on your vehicle. They are visible when you remove the wheels. There is a small window in them that allows you to see the condition of the brake pads, which if not changed when needed can lead to extensive damage to the entire braking system.

2. Check the square cut seal located on the cylinder that is located on the back of the brake casing. This is the only seal that holds the brake fluid in, so if it is compromised, it needs to be replaced immediately. Look for cracks, leaks or other signs of wear.

3. Inspect the caliper for leakage by running your fingers across the bottom of the back of it. If you come up with nothing wet, it is not leaking. If there is wetness, it is likely the brake fluid is leaking.

4. Move to the hydraulic area where the brake hoses plug in to look for rust and that the banjo fittings are in good condition. Lastly, look at the mounting studs watching for corrosion or blue-ing, both of which would indicate extreme heat.

Tips & Warnings

• Wear a protective filtering mask when working on or near the brakes, as the brake system dust can be hazardous.
• Only use brake cleaner on the brake system. Never use a petroleum-based solvent on brake system parts.
