Guys,
this may be a simple problem, but I haven't come across it before so I thought I would ask.
If I am going over 50-60 mph and have to hit my brakes to decel rapidly, my Disco pulls to the right for just the first instant of braking. Not to violent, but noticable and it gives me a scare every time. It only happens at higher speeds and only when I really have to brake quickly, not when I just ease into a normal stop. I have never had to really slam on the brakes, but am afraid this might be a big problem if I did.
It almsot seems as if my right front rotor might be grabbing before the others.
Any ideas? Is this common?
Tahnks in advance for any help.

Some possibilities that I can think of
1. Brake pads are warn down and/or uneven wear being a factor; they need to be replaced (common problem).
2. The rotors are warped.
3. Perhaps some of the rotors are worn down unevenly and needs to be resurfaced.
4. Calipers are caked with dirt to prevent moving in unison. |

yep - could very well be the problem. Pull the front wheels and check the pads - are they all wearing evenly? any contamination (fluids) on the rotors/pads (particularly the left front)? leaking calipers will cause uneven braking either from 1) loss of pressure (and braking force) due to leak or 2) actual brake fluid leaking onto the pad, which lubes the pad/rotor, which is very very bad.
DO you have stock suspension or a little bit of lift? If you're lifted, then it may just be a new fact of life (loss of castor)....non-stock trucks are just that...NON-STOCK.
hope this helps |

I had this problem at one point too. What it ended up being for me is that the piston seals in the caliper were shot and needed to be replaced. This caused my truck to pull to the oppisite side because the bad caliper was not biting on to the rotor fast enough or hard enough. I ended up replacing the seals in both front calipers. It's no that hard to do. Just messy and tedious. Not sure that this is your problem but it sounds like it.
Good Luck |

Thanks for the replies, guys. I am getting ready to do some yearly maintenance, I will check them out then.
And, Blue - I do have OME MD suspension. |

I have OME HD and I pull to the left a bit on hard braking. I used to pull to the right, but that was due to leaking caliper piston seals on the front left rotor. Replaced seals, new pads, and all is well...at least with the brakes.
Also check your trailing arm bushings...your rear axle may be floating a bit thereby letting the ass end drift to the left when you brake (resulting in front end heading to the right). |

Typically when you have a pull to the right, it is the LEFT caliper not working correctly. Why you ask?
The right one is doing its' share of the braking, but the left IS NOT. Ergo, what is commonly 'pull to the right' is really better described as 'not enough braking on the left'.
Do BOTH calipers at the same time. Seal kits-diy; closely inspect the piston for rust pitting. Inspect the rubber flex hoses-that age(MY95)it's a good time to renew them. Of course, flush and refill the entire hydralic system. Check rotors for the minimum tolerance too. Doug, 95 @ 100k |
