Hi, I haVE A 1985 Toyota 4x4. I noticed for about 2-3 months now i have to add brake fluid every couple weeks. Anyways, My question is my truck drives straight and when i press the brakes the truck does not pull to one side. Only about 3 times has it pulled to one side only when braking, and after it starts to pull to one side it goes away within a couple of minutes. I wanted to know if my brakes is leaking, could it cause my truck to pull to one side every now and then. PLease HELP ME!!!!!!!!!
