Brakes stick driver front

Ford Escape 2009 Escape 3.0 v6 136000 miles
Ive had issues for the past three years with my car done countless things to fix it and when we think we fixed the issue it comes right back. Essentially the caliper is sticking closed for some reason on the driver side front. Its got all new brakes in the front of the car: caliper, rotor, hose, pads. Have done brake flushes. Replaced the hydraulic unit. Did system updates to see if there were tech issues with the car and nothing has fixed this issue. I have dropped hundreds and hundreds of dollars into brake components and i just want the issue fixed if anyone has any issues or ideas id appreciate the help.

Same issue. Sticky right brake. Worse when the temps are eighty and above.

Found out that there are essentially “small filters” within the master cylinder that commonly get clogged and a new master fixed the issue for me

Old collapsed brake lines. Pressure from master cylinder was enough to push fluid into the brakes but not enough back pressure to release the brakes.

Have you tried doing a full brake flush to the system and seeing about contaminants in the fluid. When we’d bleed my brakes after putting a new caliper on there would be enough pressure for fluid to come out but the caliper would still end up hanging. Followed everything in line for mine caliper,hose,brake flush, abs block (dont quote me on that one) and then the master cylinder was next in line and the master was ultimately what fixed the issue and i havent had problems since.

Same problem. Was having issues with brakes hitting the floor for years, but atleast was not sticking. Now I can't even drive it cause the brake/calliper sticks front driver side after driving for 20 minutes. Problem started happening immediately after i got a full brake job, new brake booster, new rotors, shocks. Have had master cylinder replaced twice now. Mechanic telling me i either need a new master cylinder cause it's supposedly leaking AGAIN (3RD TIME) or it's the abs module (abs light is NOT on).

Truthfully even though the abs block is expensive if you wanna keep the car and be able to drive it. I’d try replacing it. Just a forwarning you it is not cheap to have replaced. The part alone coming from a ford dealership is $1,000.

@ErwinI was really hoping it was just the callipers, especially since it only started sticking after I had the brake job. If the abs light is not on then why would that be the problem?
Erwin from United States 2 years ago
@EscaperHave you tried new brake lines cause the lines are prone to collapsing in on themselves and causing the fluid to not flow through and making the caliper stick. If not try a new caliper cause sometimes they are faulty ive had a couple that were genuinely faulty.
