brake caliper Sign In

 I have a 1995 Chevy S-10 pickup and want to install the front brake calipers. I have noticed the brake caliper bolts was rounded out and not able to loosen these with a 3/8" hex key. I have tried using the vice grips on the ends of bolt and does not loosen while it slips and slide off. Please help me how to get the caliper bolts off. Any suggestions? Thank You

Re: brake caliper Sign In

This stuff is tricky to describe but I'll try what I would do:

Make double sure that it's really 3/8th Allen hex - dig it out and look if needed. It could be a Torx headed caliper bolt - perhaps #45.

Sometimes you can hammer in a sacrificial Allen or Torx that will remove the bolts. Sometimes using a metric size one larger will jam in just right for good grab OR an assortment of extractor gadgets are available specifically the outside "stud" type extractors in this case.

Plain tapping inward on the bolt can help shock it free if close with a plain hammer.

NO MATTER WHAT GETS THEM OUT GET NEW BOLTS OF COURSE,

Thank You Tom! I will try what you have suggested. It is a 3/8inch hex key. Will try the next size up.

In SAE sized next size won't even be close. Try a metric something or torx that's close.

You can also use hardened bolts if you have an assortment - have two nuts on the threads of the bolt and hammer it in - then with the double nuts tightened to each other the inside one will be stuck to work like an "make your own Allen wrench.

Some rounded/rusted crap like this take all kinds of imagination. I've gound down a tool that was too large to just the slightest too large for one time use too. Anything that works will do for a one time problem like this. Good luck,

I think those are 10mm hex.

Re: brake caliper Sign In

A pipe wrench on the end of the bolt head should loosen it. Once it grabs you'll be able to get enough torque on it to loosen it
