Customer Question

I have a 2006 Colorado. I just got it last week. After driving around for a while, the front brakes start to stick to the rotors. It feels like I'm dragging a few tons behind me. I got out and could smell brakes burning. The rims were VERY hot to the touch. Only the front brakes.
JA: Are you hoping to fix this yourself?
Customer: Yes.
JA: Great! What have you tried so far?
Customer: I have a service manual, and am fairly decent with wrenches.
JA: Is there anything else the Chevy Mechanic should be aware of about your Chevy?
Customer: No. That's the only problem. I just replaced the purge valve yesterday.
JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and connect you two.

Hello I will help you with your question,

Has any work been done to the brake system?

Does the pedal feel normal before the brakes lock?

Do the brake lights work properly?

Customer: replied 1 year ago.
I just purchased the truck last Friday. The pedal feels normal at all times. The brake lights work too.
Customer: replied 1 year ago.
It doesn't start sticking until after about an hour of driving.
Expert:  George H. replied 1 year ago.

It sounds like the master cylinder is being pressed just a bit and as the fluid heats up it cannot return through the master so it applies the front brakes.

Next time you lock them up try loosening the nuts holding the master to the booster. If the brakes release you can install a pair of washers to hold them apart or the pushrod in the booster can be shortened a bit to give it a little more play.

Try this and let me know if you have further questions

Thank you

Okay. I'll got out and give it a try. I'll have to remove the front tires first. Thanks!

Why do you have to remove the front tires?

Customer: replied 1 year ago.
my fault. I was thinking caliper. Master cylinder is under the hood. Lol!
Expert:  George H. replied 1 year ago.

You have it correct, it should just take a few turns to loosen it then you can check to see if the brakes are still locked up.

Customer: replied 1 year ago.
Okay. Thanks. I'll go check it out. A friend just suggested that I need to lubricate the caliper pins too. Thoughts?
Expert:  George H. replied 1 year ago.

Could be but you have both front brakes applying after you drive. If the calipers were stuck they wouldn't take that long. You can probably make it happen sooner if you apply the brakes firmy a few times from 40 mph using a quiet road. This will heat the fluid faster. Don't get them too hot but it should be much less than 100 miles.

That makes sense. Okay, I'm going to check the master cyl. Thanks.
Expert:  George H. replied 1 year ago.

OK< I will be here for another 4 hours tonight, let me know what you find

Thanks
