QuestionHi John:
I bought my 98 Discovery 3 months ago. I have already replaced the thermostat and just last week, a fuel pump that cost me $643. I needed front brake pads, so I took it to a brake shop. They said I needed front brake pads, rotors, and caliphers. They wanted to charge me $800. I could not afford this, so I took it to my neighbor who said I just needed pads and rotors. Those parts cost me $150. He fixed it today and as I was driving to work, I noticed that my anti lock light was still on. When it's not on and I push on the brakes, the car rattles like it's not going to stop or like I'm crunching down on something. Does this have to do with the anti lock light? Is it not supposed to be on all the time? Should I have had caliphers put on also? Or does the brake line need to be flushed? I am hoping it's not something bad because I can't afford all these repairs! The car came with no manual so I am completely clueless as to what is wrong with my car. In spite of all this, I really do love my car and just hope that I get a break from all these repairs. Thanks so much for your help.
AnswerHi Jami,
at least your fuel pump should last you another 8 to 10 years.
As for brake repairs, yes it can be costly UNLESS you can do this yourself. $150 for front rotors and pads is an excellent price (neighbour's like that are worth a bottle of wine, scotch or case of beer).
The ABS light is due to a sensor fault that has been triggered. It could be as simple as an ABS wheel sensor failure or as complicated as the ABS modulator failing. Usually, most DIY'ers pass this type of problem to the experts.
Even with the ABS light on, your brakes will work normally. If you apply your brake and you feel you are NOT stopping, then you have a problem. Could be air in the brake line somewhere. Its very important to bleed the air out of the brake line systems after major work (like rotor replacement). For myself, I rely on the two-man method and I do this several times until I am absolutely sure there is no air in the line.
If you required caliper repair work, you can save yourself big bucks by buying a caliper rebuild kit from your LR dealer. It will include (for the front) two pistons, rings and seals and is a fraction of the cost of an entire caliper. You can also opt to purchase a used caliper from a salvage yard (wrecker). Most will test the caliper BEFORE they sell it to you and include a 30 day warranty.
Now, if you apply your brakes and you hear CRUNCHING noises, it could be your ABS system working. To be sure, examine the caliper again to make sure its secured to the wheel system. Use locktite on the bolts so you know they won't come loose. Check the pads to make sure they are not being 'chewed up'. Since they're new, they should not be too worn. The rotors should be nice and smooth also...no scratches at this point.
So, make sure your brakes lines are completely free of air, the calipers are still firmly attached, the rotors and pads are still in nearly new condition. After all this is done, you should note a solid firm pressure when you apply the brake pedal. If you are feeling the ABS kicking in each time you brake, you'll have to have this problem addressed by an expert.
If the repair is too expensive, consider the option of having the ABS disconnected. I've heard that some Disco owners have done this and even remove the ABS light from the dash! Its important that your Disco have the best brakes possible and ABS is very necessary. The decision is yours.
Best of luck,

NB: do yourself a favour, buy the Haynes manual for your Disco #3016. Most auto parts shops can order this for you. Great book for DIY Disco owners. Under $50. Lots of photos and simple instructions.
