What size torque wrench for brakes?

It is critical to select the proper torque wrench for the job. A torque wrench with a 1/2-inch drive will be sufficient for most brake jobs. 

If you’re tightening or loosening brakes out of service for a long time, a 1-inch drive torque wrench could come in handy.

A 1-inch drive torque wrench is generally more accurate than a 1/ 2-inch drive wrench and allows for higher torque levels without being affected by the stiffness of the bolts.

Torque wrenches are available in many sizes, from 1/ 2-inch to 1-inch drive. The drive size is measured inches from the end of the handle to the tip of the jaw. The larger the drive size, the more accurate the wrench will be.

The bolts should tighten to your car’s owner’s manual specifications. You can usually find the specifications online if you still need the owner’s manual.

How much torque does it take to tighten a brake caliper?

When it comes to brakes, it is essential to ensure they are properly tightened. This can be done using a torque wrench. For most brake calipers, it takes between 20 and 30 foot-pounds of torque to tighten them properly. An ordinary wrench will suffice if you don’t have a torque wrench.

When not to use an Impact wrench?

There are several situations when you should n’t use an impact wrench:

  1. When you have a screw stuck on a drill bit, you must stop drilling to remove it.

Frequently Asked Questions

What happens if you over-tighten the caliper bolts?

This can be fatal, and you can cause the caliper to fail under severe conditions. It is important to loosen the bolt just enough to get the caliper adjusted properly and then tighten it back up after you’ve checked it to be sure it’s tightened correctly. The caliper can break off or bend the wheel axle if you don’t.

Can you hand tighten caliper bolts?

You can hand-tighten caliper bolts. But it requires a good amount of experience and practice. Make sure to follow instructions on how to do it correctly, and consult with your mechanic to ensure the correct procedure.

How tight do you tighten brake lines?

When tightening the brake lines, you should remove the brake pads and the lining to prevent damage to the line, as tightening it too tight will cause the line to leak, which may damage your brake assembly.

Then, it would help if you loosened the nut with a ratchet or a wrench to ensure the nut is properly tightened while still being loose enough to allow you to tighten it with a torque wrench. Finally, once the brake has been reassembled, you should tighten the nut up to 20-30 pounds of torque to ensure that the brake lines will not leak.

Can you over tighten caliper pins?

This may not be a good idea. The pins may break off and damage your rims. To avoid this, you should always give the caliper the correct amount of pressure when tightening it, so that it doesn’t break the pin off.


In conclusion, both disc and drum brakes require the use of a torque wrench. For detailed guidelines about adjusting the nuts or hinges for your particular vehicle, consult the owner’s handbook you received with your automobile.

Only with accurate info and equipment can you complete essential maintenance quickly and affordably, preventing costly damages!
