2014 Chevy Silverado 1500 Brake Issue

Paul Koval · June 25, 2020

Hello to all.
I have recently stumbled upon a problem with my Chevy Silverado where my front driver side caliper is locking while after driving and pressing on the brakes a couple of times, the brake pedal was very tight and I couldn’t even push it down anymore. I pulled over on the side of the road and was able to release the pressure by opening the bleeder on the caliper a little. Luckily I was close to the house so I was able to make it back home.
After I came home I replaced the caliper and the break hose on the front driver side but when I went for a test drive I got the same problem where the front driver brake would lock up after pressing on the brakes.
Any idea of what could be going on?

Are you sure it is just the drivers side front? The reason I ask is if the passenger side front it also locked up but removing the bleeder valve on the drivers side also relieves the pressure from the passenger side as well. This would be a fault with the Master cylinder. I have run into that in the past.

Today when I drove it again and got it really locked up I did notice that passenger side also got pretty hot so I would think that it as well is locking up. But driver side gets much hotter. Also the rear wheels don’t get hot whatsoever.
While doing some testing and the front was locked up I was able to release the pressure by releasing master cylinder front port and it after I drove some more I was able to release with the rear port, not sure is this means anything. Just putting it out there

You have a bad master cylinder. I did one of these not to long ago.
