How to diagnose a locked up brake caliper
In this video I'll show you how to properly diagnose a locked up brake caliper. Usually, when brakes lock up on one wheel its caused by either a locked up caliper piston, stuck caliper slide pins, or a clogged flex hose going to the caliper. In this video you will find out how to test each of these components in order to get an acurate diagnosis of your brake problem. Please note: Caliper pistons made of phenolic material can be brittle and break when pried against. It is recommended to use a caliper piston Comte's so on these type calipers to prevent damage to the pistons.

Possible culprit when your brake caliper is sticking on your vehicle.
If you have a brake caliper sticking. Or even a new replacement one sticking. It is a good possibility it is the hose. I went online and saw mechanics talking about a hose can work as a check valve. But evena mechanic buddy of mine never saw one do what mine did. This can likely be a real issue if you live in a State that uses road salt. I drive my truck on some saltwater beaches. So its about the same thing. Hope this video helps someone getting frustrated by braking issues. Apologize for the shaky video. Camera has zero stabilization.
