I recently purchased a 1999 discovery 1 and everything was perfect everything was fine. Recently, well today the brakes just stopped working. Of course I went through all the threads here in the forums for this problem but no sauce.

i of course started with bleeding the brakes just to see what happened. I realized that I wasn’t getting any fluid out of either of the rear calipers. The front two were sort of shotty too. I inspected all my brake lines, no fluid on the ground or lines and no hissing sounds.

I thought maybe I’d replace the master cylinder. Did that with no luck. Brake pedal will sort of build pressure then lose it. When I say “sort of” it’s very slight. I do not know what else to do. Even with fluid pissing out of both front calipers I still get little to no pressure on the brake pedal. Should i replace the booster? I don’t understand what’s going on..

if anyone has any information about this please call or text me @ 803-673-4663

 

Robert you should post your technical questions in the Disco 1 section of this forum.

 

Check to make sure your calipers aren't seeping fluid, then you have a F/R Valve. I had a similar issue on a 95 D1 that someone completely gutted the entire brake system trying to figure it out. Turns out the MC was bad all along (the one part the hadn't touched).
