Thread: Bleeding brakes

Major grumps.

Have been bleeding the brakes on the 98 V8 all day. Put through 1.5 litres of Blue fluid (old was yellow about 5 years old) using my Gunsons Eezibleed to change the fluid. Didn't pay a lot of attention to the old fluid coming out until it was all blue. But then realised I was getting a lot of air coming through the system. Previously brakes were not awe inspiring but seemed to work OK. So I put the wheels back on took it for a drive to check it out and the brakes actually seemed a bit better than they were before. Not happy with the amount of air bubbles I had seen, back on the jackstands and started bleeding again. After running 0.5 Litre twice (reusing the same fluid each time) through each wheel still lots of air coming through, got bored and just kept bleeding the Left rear while I got on with other maintenance tasks like changing a track rod end and greasing all the UJs. After about 10 bleeds (about 5 litres) at the left rear I had to add another 0.25 litre of fluid to my bottle suggesting that I had actually got rid of 0.25 litre of air. Carried on bleeding at the left rear - another 10 times (5 litres) and still getting air bubbles coming out. Now I am stumped.

The only odd thing I have found is that the pedal is actually quite hard to push down even when the bleed nipple is open.

Have i stumbled upon a gold mine of air in the ABS system that has been there for the whole time I have owned this Disco ?

FWIW - brake flexis were changed about 8 years ago along with brake fluid reservoir. Didn't have any issues I can remember bleeding the brakes then.

Tried to bleed it's system and only found air in the front right, but it was unending. The Disco is still stoppable, but at the moment the brakes can be spongy at times.
