Hi
I have a 1998 mazda b2500d turbodiesel 4x4 doublecab pic-up. When I apply brakes, the one rear wheel locks.I cannot attemt to drive in wet conditions as this happens much easier then.I had the truck's brakes adjusted, but this still happens. Before it was left rear, after adjustment it's right rear. What can the problem be and how can I fix this?It is my only vehicle and I am quite desperate by now.

Many thanks

The adjustment is incorrect. Did you check the brake drums for wear?
Were the front brakes checked?

I can't really see wear on the drums, and brakepads are almost new(replaced 8months ago, front brakes too. Driving today, braked did not lock, but later this afternoon, and last night again it did

Is your vehicle equipped with ABS?
Is there any sign of leaks at the rear cylinders?
How did you adjust the rear shoes?
How many notches of the handbrake lever when it is applied?

No abs, but there is a load sensor
a bit wet round thecylinders of the brakes in the hubs
a mechanic adjusted the braker for me
about 4 notches on the handbrake

Contaminations due to brake fluids can cause the shoes to grab.

Check the load sensing valve. If it is out of adjustment or faulty, it can result in the rear brakes getting too much pressure.

I have no idea how to set the load valve.I have had the truck at a few places and no one can help.I will also replace the seals and see if that does any good.

Remember to clean the shoes and drum of any resudual fluid contaminations.
