94 Toyot Hilux brake problem?

Sounds like one side is working too good, or the other side is not working well enough. Unless you’ve just had brake work done, I would assume one side is not working well enough.

Take the wheels off and check for signs of leaking brake fluid.

I would check the drum brakes first. You may have a leaking wheel cylinder. They are inexpensive to repair, I rebuilt one with the help of a neighbor who was an auto repair instructor at a technical high school in the area. The cost was less than $10 for the rebuild kit.

Pulling brakes could also be caused by something that is on the brake pad such as oil or fluid. If the brake pads are wet with fluid they should probably be replaced. (After you solve the problem of the leak of course)

In the US the 4wd version of the hilux has 4 piston calipers and the 2wd has one piston sliding calipers. The 4 piston calipers begin to bind up and 1 or the other pistons stops moving so there is less effect on that side and the overall braking decreases. On my 1988 4runner what you may call a Surf, the inner pistons on one side stopped working and as a result the side of the brake rotor that you can see through the wheel looks fine but the inside is making less to no contact and if you continue to drive that way long enough it can get really rusty from lack of use but but still sort of stop. Here, there are enough of these trucks around that rebuilt calipers are very affordable for both the 4piston and single piston calipers. If you have the single piston caliper a sticking slide can make the brake half work like the 4piston.
The single piston caliper can stick on. This makes the car brake more to one side because one caliper is dragging and is hot and ready to go I guess. If after driving you can sort of roll to a stop and get out and feel of the wheels a hot wheel has a dragging caliper. Note this can be really hot.

I’ve never known a problem in the rear brakes to cause a pull. I’m not saying it can’t happen, just that I’ve never seen it. I would imagine that you’ve got a front caliper that’s starting to hang up, which is common with those calipers. The way I’d check is I’d raise the front of the truck, support it safely on jack stands and then see if the front wheels turn easily. If one side won’t turn at all by hand, or is very difficult to turn by hand, thiat’s the side that most likely has a dragging brake.

Keep in mind that I was referring to a leak (perhaps at a wheel cylinder) that would also cause the opisite front wheel not to get pressure because of the ‘split diaganal’ design.
