My front driver side brakes rattle. I know why they rattle. They rattle because the pins that hold the pads in are loose in the caliper holes and this allows for the pads to move around. We tried new pins, but they are loose as well. It would seem that the holes in the calipers have worn larger. Has anybody had this problem before? Is there a fix other than installing new calipers?
This is also, I believe, the reason my brakes will squeel while driving at highways speeds. I believe that the pads are able to move enough that at high speeds they vibrate against the rotors causing the squeel.
Thanks for any advice!

Jeremy,
If you figure it out, let me know, cause my 2001 DII with only 5900 miles on it does teh same thing. On a cobble stone street you would think the truck was falling appart they rattle and squeek so much. I initially thought mine was the shocks, but have narrowed it down to the brakes. Mine is not too bad when driving on a smooth surface, but I can hear an intermittant "squeek" of sorts, and on bumps there is a slight rattle you can feel/hear.
I'll keep my eye on this post.

With the tire off, I could turn the rotor/hub forward and backward and the pads would try to go in the direction of the turning rotor and cause a clanking when changing directions. My pins would actually move within the holes of the caliper. I would think the pins should be tight enough to keep the pads in a stationary position. All I can fathom is that the holes in the calipers have grown over the miles of braking allowing for this movement.
Does anybody know if they make larger pins for the Discovery? That would solve my problem as well. |

I'll speak for Rico here, but if you put high-temp grease the pins, you won't be able to hear the rattle. Also, Discount Rovers has the pin kits available at a reasonable price.
Thanks,

It has nothing to do with the pins. I had the same problem on mine and it turned out to be the pads. The LR pads have an extra backing on them wich makes them fit tighter. If you are already using LR pads, then disregard this, but I had the same problem and I assumed the springs were too weak so I replaced them, then I replaced the pins and it made no difference. Once I put the LR pads in (they came with new springs) the rattle went away. Again, if you are using LR brand pads, obviously, this is not your solution. |

I have seen aftermarket pads where the holes were not round, but more egg-shaped. Other aftermarket pads I've seen have round holes and don't make the noise the others do.
It seems as though the caliper will allow the pad to move up and down as the rotor turns-I considered fabbing a part to hold the pad, but just told the driver of the car to live with it, it's normal for a Rover. That's what the dealer would have said, right? |

i have a similar prblem on my 01 DiscoII, but without the squeak. whenever i have to depress the break with alot of pressure and i happen to be going over a bump of any size, the brake pedal "shimmys" or shakes pretty violently under my foot.
any ideas? |

LOL - dealer would have said that only after replacing rotors, pads, and a few seals here and there. |

I would imagine that the problem with the shimmering brake pedal is the abs system. |

Does anybody recall as they were installing new pads if the pin fits the hole in the caliper snuggly or did it have a lot of play? Mine seemed to have a lot of play. I didn't put on new pins since the existing ones didn't appear to be worn down. The springs are new.
I don't recall the brand of pads on my Disco, but I do know they had the egg shaped holes. That could be part of the issue. Maybe I'll change out my pads again and get some with round holes instead? |

I've replaced pads 3 times so far on mine, with different brands and, if i recall correctly, they all had play in the pin holes. . |

Check your caliper pistons for freedom of movement - if they hang up, it can cause the pads to move when not braking. I've run pads with no anti-squeal pads for quite some time with no problems, so definitely don't count on "genuine" pads solving the problem.
