If you have a car that has a front (passenger side) caliper hanging up and just change out the caliper and new pads on both sides, why would the drivers side now lock up under heavy braking? I'm guessing that the rotor on the P side may have been affected by glazing of the pads? Ideas?
Dude the brake hose is deteriorated and is trapping pressure.
Happens all the time on late model vehicles. Starts showing up as one side wearing faster than the other. They don't like the heat.
Change the hoses and your good to go.
