What Size Allen Wrench For Chevy Brake Calipers?

If you’re wondering what size Allen wrench is needed for Chevy brake calipers, the answer may surprise you. There is no one-size-fits-all answer to this question, as the size of the Allen wrench required will depend on the specific model and year of your Chevy car or truck. However, let us give you some thumb rules.

For most models of Chevrolet cars and trucks, the recommended size Allen wrench for brake calipers is 3/8″. If you have a smaller or larger model of Chevrolet, you may need to use a different size Allen wrench.

What Tools Do You Need To Replace A Brake Caliper?

To replace a brake caliper, you will need:

  • A socket wrench and ratchet
  • A set of metric sockets
  • A C-clamp or brake bleeding kit
  • Brake pads
  • Brake caliper lubricant
  • A screwdriver

Here’s a step by step guide on what to do:

  • First, remove the old brake pads from the caliper. Next, use the socket wrench to remove the caliper’s bolts. Be careful not to lose any of the small parts. 
  • Once the caliper is free, remove the old brake fluid from the reservoir using a turkey baster or syringe. Clean out any debris from around the reservoir with a cloth. 
  • Now, take your new brake pads and apply a thin layer of brake caliper lubricant to the back. Slide the new pads into the caliper, ensuring they are correctly seated. This will help them slide into place more easily. 
  • Use the C-clamp or brake bleeding kit to compress the caliper pistons. This will make it easier to bolt the caliper back into place. 
  • Once the new pads are in place and the caliper is compressed, bolt it back into position using your socket wrench. Be sure not to overtighten the bolts. 
  • Finally, add new brake fluid to the reservoir and bleed the brakes according to your car’s specifications. You may need a friend’s help for this step.

How Do You Remove Brake Calipers?

Caliper bolts are used to hold the brake calipers in place. The bolts can be different sizes, and it is essential to know if your vehicle has the same size bolts for each caliper so that you can replace them with uniform-sized replacement parts.

Most vehicles use a standard 6mm x 1.0 metric threaded bolt to secure their brake calipers. The caliper bolts on every part of your car’s braking system will have this exact size and threading pattern. 

However, there may be variations between manufacturers or models, particularly among older or foreign vehicles. Some cars may also have different-sized bolts on each side, requiring you to use two different-sized replacements when changing a caliper due to a malfunction or damage.

Changing a brake caliper can be tricky, but with the right tools and some basic knowledge of car mechanics. This article will cover everything you need to know about changing a brake caliper on a Chevy truck, including how to remove and install new calipers safely.
