2011 Silverado 1500 dragging brakes?

[ryancz33]

New to the forum. Just got me a 2011 Silverado 1500 (rear drums) from a buddy about to PCS. Truck drove perfect, had a few minor electrical issues here and there but fixed everything and all was well for a while. Recently started attacking a brake dragging issue. I’d say I’m pretty mechanically inclined but this has me completely stumped. It’s only the front brakes that lock up and smoke out. I suspected an abs module malfunction so had that replaced and it’s still dragging. It happens mostly when driving 10+ miles. Pedal gets incredibly hard. I’ve read different forums but none were clear to me. I don’t know if I should start with simple brake lines or brake booster? Has anybody else experienced this?

Both fronts, or just one?

 

Either way, if the hoses are old / original, this could be the issue. Sometimes the inside collapses and will act like a check valve, and won't allow fluid to return when the pedal is released. Heat will compound the problem when the fluid expands, and the cycle continues to get worse.

 

Check inside the master cylinder reservoir and make sure it's clean. Sometimes gunk / sludge can plug up orifices in there causing a blockage of returning fluid. Especially if it had sat more than a few months in a humid environment, and if the fluid has never been changed from day 1.

 

Those are the cheap & easy first steps.

 

Second culprit could be crappy / old calipers. At this age there's a good chance they've been replaced at least once already, especially if from the salt belt, and usually with low quality remans. 

 

Before winging a pair of calipers at it, check the slide pins and make sure they are RUST FREE, AND lubricated. The caliper should move freely from side to side relative to the rotor (left to right from the driver's seat). If they're dry and/or rusted, wire wheel them clean and lube them up. See if that works, and if not, some new calipers may be needed if the hoses don't fix the issue.

I did replace the front right caliper pretty recently, as the first time it happened, 2nd time it happened it was both front. This would be about the 4th time this has happened. I got it AAA to the shop, I was looking at the brake hose issues, and that’s the next cheapest option. I also seen that a flooded brake booster could cause that. Thanks for the insight jsdirt!

It would be coincidental for both front brake hoses or calipers to fail at the same time. There is an old thread on here of similar a similar issue, not sure how best to direct you to it - but I would be looking at the brake booster.

I'd say a master cylinder could do this more so than the booster. The booster is just a mechanical assist to the master so that you don't have to use two feet on the pedal every time you stop.

 

Also, ABS units with sticky check valves can cause this as well.

Yes, with two older Chevys. One case both front brake lines. The other one front line and rear caliper.
