Truck pulls right when pressing brakes....

I noticed my truck pulling right severly when depressing the brake pedal heavily the other day. Feels like the right front brakes are locking or something. It seems to happen when traveling on a bumpy road or off roading.

This doesn't happen anyother time but when press the pedal hard and it is an uneven surface or off roading.

Any advice?

Thanks

On dirt or loose surface do you notice any one wheel locking up or skidding more than the others? One thing you should check is the adjustment of the rears. Sometimes they can get out when one side quits adjusting or over adjusts. Have you had brake work done lately? How many miles do you have?

 

Lots of reasons but it boils down to this, you have more friction on one side then another. Rotor warpage, oil on the pads, water on the pads, uneven wear, leak in brake line, etc. Take off the wheels and look for fluid leaking and pad wear. Spin the rotor by hand and notice if it pulls away from the pad at a certain location. Alignment and mechanical breakage can affect it also but usually not as common.

Brake pads are cheap and easy to the DIY guy. It would be worth doing that before taking it to a mechanic.

 

I'd start with the most simple possibility, check the tire pressure. If one tire is at a noticably lower pressure that may be your problem. If both fronts tires are at the same pressure then it's time to check the brakes, then aligment.

 

Thanks to all for your help. No oil leakage or water, brake pads are fine...had a friend, who worked at toyota a while back, check the pads and spin the tires with no definite problem. The truck has about 50,000 miles. Tire pressure is fine.

The alignment is a little off, pulling to the left but nothing major. Gonna' try aligning and see what happens. Another friend mentioned it might be air in the front, right brake line. Hope aligning works.
