I have owned my disco II for close to 3 years now and I have been experiencing a spongy brake peddle for the past 2 months. When I step on the brakes, I feel like I am stopping 1/2 to a full car length longer than normal. I find that if I pump the brakes, one or more times, I get a great/normal reaction from the brakes.
I had my front and rear brakes pads replaced at the dealership 9,600 miles ago. I have it at the deal now and they are telling me that my rear pads have 15% left on them and my fronts have 50%. 35% difference. They suggest I replace the rears within the next 3,000 miles. How long do brakes LR brakes last? I thought the fronts go first?
The dealership is telling me that there is nothing wrong with the brakes, and that it is typical for the rear brakes to wear first on Discos.
I talked with another LR mechanic and he raised some red flags. One, brakes pads might be defective with only 9,600. Two, if the rears are wearing faster than the front, sound like the rears are compensation for the fronts not working properly, i.e. air bubbles in the lines.
My wife drives the disco to/from work on flat paved surface, round trip 5 miles. We do not tow anything or put a lot of stress on the vehicle.
Anyone have any thoughts??? |

Pads, especially in the rear, should last longer than that. It's a good thing to change the front pads more frequently than you would on another car to keep from getting into the rotor, but it's shouldn't be THAT quick.
The rears usually are changed about every other time that the fronts are... they do NOT wear out faster than the fronts.
If you're pumping the brakes and improving the response, I'd change your brake fluid and bleed them well.
FWIW...

The rears went first on my 99 D2 at 30k. I also found it odd that they gave it up first...You're pig sees the same action as mine...seems very strange that your looking at 15k before you'll need new pads (and rotors) in the rear. Does your wife left foot brake ? Or do you think you may have some sticking calipers back there that could cause this excessive wear ? |

I had to change the rear pads on 2001 DII at 30k also...strange...fronts are still in good shape

"The dealership is telling me that there is nothing wrong with the brakes, and that it is typical for the rear brakes to wear first on Discos." I'd get that in writing!!
Just a guess but maybe the brake servo/ master cylinder is bad and leaking out somwehere so you need more pedal to power it back up ?? Any drop in your brake fluid level after all that pumping? Any bubles in the resevoir after pumping which might indicate a high pressure break where it only leaks when you hit the pedal?
The primary and secondary brake circuits could be buggered-up and sending all the power to the rear too.. again just a guess.
Get new brake fluid and a good bleed, then you can take that out of the equation. |

It seem sthat after all the problems, quirks and idiosyncracies, we would have learned that Land Rovers are not like other autos.
My simple understanding is: The rears are significantly smaller than the fronts and the braking system attempts to reduce the amount of "nose dive" under braking. I assume by applying more pressure or such to the rears.
From everything I have read/seen, it is very common for the rears to wear fatser than the fronts, at least on the DII. |

My experience is the rear brakes wear faster than the front brakes on a Disco II. Another factor to consider is the Disco II has ETC. If your wife is heavy on the gas under wet or uneven pavement the ETC will kick in and use the brakes to slow the wheel from spinning. ETC could cause premature brake pad wear especially if you off-road alot. Just a possibility. |

ROFL... the image of a D2 laying rubber just came to mind after reading that. |

My D1 has also got through rear pads in 50kkms but the fronts still have a way to go. I'd been beginning to think the dealer had replaced them without billing me!
Another mystery explained by discoweb........ |
