brakes on and when you drive the car the front left

distribution block any help would be appreciated

It needs to have a proportioning valve(adjusts hydraulic pressue bias to wheels) and or the correct disk brake master cylinder installed if it was not changed during these modifications.

Thank you I will check them things out Monday


A bad brake hose will cause your problem also. Do this test with caliper locked up remove wheel and loosen bleeder screw until brake fluid comes out of hole in bleeder screw then try turning rotor if it spins freely bad brake hose if it stays tight piston in caliper has seized up but we know it is not that since you replaced with new caliper. Question how long have you had the vehicle before this has start happening ?
