I have a problem with my 1997 Land Rover Discoverys breaks. Once in a wile when you press the breaks nothing happens. The peddle is rock solid. This problem only happens every so often. i have had the ABS pump replaced but this has not cured the problem

GPS receiver module may be faulty.

Bad brake booster (diaphram defective) or bad check valve on booster housing.

This can sometimes happen when the brake sensor is not being activated. If you press *really* hard on the brake, you can sometimes get it to trip, allowing you to get out of park. Generally, the sensor will have to be replaced, but I have had one car (2002 Ford Explorer) where this trick would make it work for months at a time.

sounds like the booster is going bad

big job but doable.
welding in new 50x100 3mm box section instead of soft sills as this wont rot out and you get funky rock sliders built in!
bit of fabricating of body to chassis mounts but no harder than welding in after market panels. good pics on lr4x4 forum.

take it to a workshop that either can repair automatic transmissions or manual transmissions, i dont know hich because you dont say what type of gearbox you have. If its a manual, then is the clutch faulty ? if its automatic then do you have any oil in the gearbox ?

it's an odd occurance but it sounds like the hydraulic fluid in the clutch lined may have boiled. it's usually okay once it's cooled down, but if the pedal feels weird you may want to bleed your line.

brake swith at the brake pedal.
both mine and my wifes Land rovers did the same thing.
once replaced car would go into gear.
do your brake lights stay on no matter pressing or not?

hi Mattperez831.
this is all i could find out from the internet.
check.
crank sensor,Fuel pump, ignition coil is getting hot,.
A "main" relay can control multiple circuits, primarily for the ignition..
advise to him was to change the ignition module..
coil pack..
