Default Bad Brake Hose? Bad Caliper?

So. I replaced my brake pads 2 weeks ago and yesterday I noticed a burning smell of brake. So i checked my rear passenger wheel and it was really tough to turn compared to the rear driver side. I pull off the rear passenger caliper and BAM pads are toast. So I clearly have a sticky caliper...

I tried to compress the piston and it was really tough but it compressed. I built up pressure in the lines by stepping on the brake pedal like 20 times and tried it again but this time I cracked the bleeder and it was alot easier to compress..?

any thoughts?

My buddy told me it could be the e-brake but I don't think it is.

Wrong forum. For future reference, POWERTRAIN refers to the motor.

Edit: Onto your problem, you likely need to replace or rebuild the caliper. It's frozen.

If the caliper compressed when the bleeder was cracked, its not frozen.

Does it move on the slides properly?

Are there any kinks in the hose?

What you are describing (I tried to compress the piston and it was really tough but it compressed. I built up pressure in the lines by stepping on the brake pedal like 20 times and tried it again but this time I cracked the bleeder and it was alot easier to compress..?) is exactly how a single piston caliper behaves. What were you using to compress the caliper?

How can I tell if its moving on the slides properly? I lubed them up and they move in and out very freely.

Sounds like your caliper is fine. Using the channel locks you are potentially pushing the piston in crooked making it extra difficult. Use a C-clamp (or a brake caliper tool)

Thanks, appreciate your help. So before I avoid burning up brand new pads again what do you suggest I do?

Are the pads tight in the caliper bracket? They should be able to slide in and out freely. Sounds like your pads are a hair too big and are sticking here.

turns out the rust from me compressing the piston when I changed the caliper got caught under and in the piston cylinder preventing the piston to compress away from the pads. 90 dollars later new pads and a caliper shes good to go.
