How to Prevent the Front Brake Caliper from Sticking

automobileglobe.comIf you tend to ignore any front brake repair signs and issues that you may have, you will wear out the pads and rotors about too soon. This will then result in more costly repairs that could have been handled beforehand. One of the issues that is quite common for many people front calipers that stick. This can occur because of simple dirt, rust, or pads that are not functioning properly. If you are seeing a problem with your brake calipers, here are the steps to take to keep them from sticking.

Step 1 – Raise Front End of the Vehicle

To get at the brake caliper you are going to have to remove the front tire. Loosen each lug nug slightly before jacking up the car. Use a heavy-duty floor jack and start raising the front end of the car off the floor. Put a jack stand, one on each side, on the frame of the car, right behind the wheels, to keep the vehicle secure while in the air. Never rely on the use of a jack to keep the vehicle suspended.

Step 2 – Take out the Tire

Once the vehicle is lifted in the air you can then use an impact wrench to remove the lug nuts from your front tire. Many newer cars have at least one locking lug nut that needs a key, typically found in your glovebox or near the spare tire. Keep the lug nuts together so you will know where they are when you have finished the project. Grab the tire and slide it off the of the lugs and put in an area away from the work space.

Step 3 – Spray Brake Cleaner

One way to keep your brake calipers from sticking is to provide them a good spray with brake cleaner. There are times when road dirt, brake dust, and other particles will get into the calipers making them to “gum” up and stick. Brake cleaner will assist penetrate into the calipers and loosen them up.

Step 4 – Take out Calipers

Using your socket wrench,take the caliper off of the brake pad and rotor. Do not suspend the caliper with the brake line only. This can make the line to break, or leaks to form. Hold it with a short piece of string or a bungee cord.

Step 5 – Sand The Brake Pads

Once the caliper is free of the rotor you can pry out the brake pads. Sometimes rust will accumulate on the edges of the brake pad and cause the caliper to stick. Once you have the pad in your hands, use some 500 grit sandpaper and sand off any rust, or dirt. Sand it down until you see bare metal on the pad. Put them back in the brake caliper after you have finished.

Step 6 – Clean Pins in Caliper

A simple pin found in the caliper can get dirty with grease and cause the whole assembly to stick. Use some anti-seize fluid on the pins and put them back into position.

Step 7 – Replace the Calipers

Compress the calipers with a clamp and put it back onto the rotor.

Step 8 – Press Brake Pedal

Have someone press the brake pedal a few times to be sure that the calipers are functioning properly and are not sticking the rotor. Adjust the calipers as required. Then put the tire back on and lower the vehicle back down.This should put an end to your car problem with brake.
