As soon as my truck heats up my front brakes start locking up. I have replaced the booster master cylinder, rubber hoses, calipers, reproportion valve and block and the ABS computer box and they are still locking up as soon as the truck runs a few miles. Can somebody help me please? Desperate forgot to mention also change the rubber brake hoses both sides.

This is an odd one based on what you replaced. So let's take a step back and prove that this is both front wheels by getting them to lock up and then lift the vehicle on jack stands and see exactly which wheels are locked up.

When the wheel is locked, can you brake the bleeder loose and see if it releases. If it does then this is a hydraulic issue.

Then we need to confirm what type of brake fluid you are using.

Lastly we may need to flush the fluid just to be sure but let's start with this and go from there. Thanks
