I changed the calipers, brake hose, and they can't seem to find the problem. it has happen since I changed my brake booster. I already spend over $2,000,00 and they can't find the problem.

Good morning,

Have the pads and rotors been replaced at the same time as the calipers and hoses?

Unequal pressure to the wheels can cause this from the master cylinder.

Also, the ABS should prevent any lock up of the wheels. Do you have any codes stored for the ABS system?

It sounds like you may have air in the system.

You need to have them recheck the system. Something is missing here.

Getting tired of this. my last resort is trading in the car which I definitely don't want to do but it's getting to the point.

You need to have someone else give you another opinion of the reason why this is happening.

Locking up the wheels is never right.

Wish I was there to help, I would have found the issue.
