This is a problem that I am very familiar with as I had the same problem on a 79 chevy van. After scratching my head for a couple days I decided that the only thing I had not replaced was the rubber lines........ I did and they worked perfect

2005 Chevy Equinox left front brake caliper locks up


Your vehicle should have rear drum brakes...They have to be adjusted manually for correct adjustment...People say they self adjust but it is not good enough....by adjusting the rear it will decrease the pressure on the front and deliver equal braking...This will help eliminate caliper pressure overload....I'm not saying that is your caliper problem but it is insult to injury and will save the life of front brakes.....Now your caliper problem..FYI..A rule of thumb is anytime you change a caliper you should always replace both calipers to have identical braking pressure".The same with brake hoses and rear wheel cylinders.....The caliper that froze in the first place got hot and boiled the brake fluid and quite possibly partially collapsed the caliper brake line/hose inside as Clint and Frank stated....I am going to guess that the first caliper froze under normal conditions however got hot enough to internally damage the caliper line/hose...Then you may think of the pressure regulator being bad in which case could be a problem......So this is what you do".Since we know the left front caliper line/hose has been exposed to heat it needs to be replaced anyway...also the fluid was boiled and it needs to be changed / bled...The new caliper that froze should be ok unless it was bad off the shelf which is rare but possible."..Change the line/hose,bleed the brake system and let the mechanic test drive before you pay and leave..The mechanic will know before driving if the new caliper that froze is bad or not by rotating the wheel...This is the cheapest way...And you will know if the pressure regulator is bad or not just by bleeding system........I hope this helps....."Brooks/Metalpoet....."....

2007 F350 4X4 front brakes are dragging, has produced heat high enough to melt the seals on the calipers. What can cause this issue. Brake pedal is normal, no warning lights are on, rear brakes appear to...


Well, it can be the caliper itself sticking, or it could be defective brake hoses. If it is affecting both sides equally, then it could even be a defective brake master cylinder or a malfunctioning Antilock Brake unit. To hep determine what the cause is, jack the vehicle up and make sure it is properly supported. Remove the front wheels. Get in the vehicle and start the engine. Press HARD on the brake pedal, then shut the engine off and get out and check to see if you can turn the wheel hubs by hand. If they will not move, open the brake bleeder on the caliper and see if brake fluid squirts out under pressure and see if this causes the brakes to release. If they still won't move you need to replace your calipers. If they release, then I would try replacing the rubber brake hoses to the calipers. (They can collapse internally and keep the calipers applied - you cannot see this by visual inspection.) If replacing the hoses does not make the vehicle pass the test above, then you need to have your ABS Module and your Master Cylinder tested.

Hello: You nare going to have to replace/rebuild front calipers, replace Both rubber hoses that go fron the frame to the calipers. You may have to replace the rubber hoses in the rear and the rear wheel cylinders. Contaminated brake fluid creates a expensive and long repair.

Front brakes stay locked up


You may want to replace your flexible feed lines to the calipers. Any little bit of **** in them will not let the brake fluid out of the caliper,

Hot front wheels


Replace brake hoses,they have an inner core that has ruptured and the outside rubber core is keeping pressure on the caliper with you foot off the brake. This will fix it! A common problem for this vehicle.
