Why does your brake keep getting hot you have replaced your brakes brake caliper and your brake line Can a loose ball joint cause this?

Answer 1

Check the bearings. The end play in a bearing could cause the axle to extend and wear the pads out prematurely.

Contaminated brake fluid will cause this problem. As fluid heats up do to pads riding on rotors, contaminated fluid will expand causing brake pads to increase pressure against rotor and heating.

Answer 2

Not as a rule, but you didn't mention replacing the rotor, if it has worn too thin it will heat up quickly, if you have been having issues with that side it is possible that it has worn more than the others.

Answer 3

Another possible cause, which is the most common, is corroded or rusty caliber slide pins. Remove them and look for rust or corrosion. If it is not possible to clean them until they look almost new then you should buy new ones. Lubricate them with brake lube before reinstalling. In addition how do you know they are overheating? Discs get very hot even when everything is normal. Normal brakes will burn you finger when they are working just fine. The only sure way to know is of course if they are glowing red or it there is 20 degrees difference between the rotors. You can check this with a infra-red thermometer.

Answer 4

If you have one wheel that the brakes run hot on and everything seems to check okay, check the brake hose. They can collapse internally and create a check valve. One way to check for that condition would be to open the bleeder valve immediately after a drive and the brake has heated up. If brake fluid squirts out and pressure releases you probably have a bad brake hose.
