How to adjust brakes on a cat d5m - Caterpillar Norscot 1/87 Cat D5m Lgp Track Type Bulldozer Tractr Ho

check wire harness for short

Possibly just your linkage from activator the master cylinder is in to far and not allowing it to bleed back because it's holding the brake on still when you've released/off brake. Adjust it out from the master cylinder until it's loose just a touch.

if it is an EFI vehicle then run the fault codes to check for sensor problems
check for a failed cat converter blocking the exhaust
check for dragging brakes especially the front callipers

Jets are replaceable but not really adjustable.You can adjust the air screw,start at a turn and a half out.

This question got put under shoes. If the manual says the pressure should be 800 psi, then run with that. This sounds like a challenge and the manual is more of a friend than me!

i have 8000# fork lift when we apply brakes you have to go in oppisite directions to move again(the brakes stick) an also it has very sensitive brakes kind of scary

Brake pedal traveling to the floor is air in the system or a failing brake booster.

Poor acceleration could be a clogged cat. You would have to remove it to know for sure.

Have the rotor turned down or replaced, and have that calipar checked, it might be seized up.

check in your fuse panel there are white pop out circuit breakes see if one is poped out push back in should fix your problem
