Hi all,
Tried to post in another forum with no success.
Just wondered if you can help.
I have had my Defender 300TDi for about 18Mths, since then the brakes have never been very good. when purchased I had to change both front calipers due to seized pistons.
While trying to bleed the Front calipers, there is a steady stream of air on both front calipers, Also, While braking initial application of the brake pedal goes half way to the floor with very little braking. additional pedal presses the pedal goes firmer and braking efficiency is increased.
I have changed the Non Return Valve, Checked their is vacuum from the vacuum hose from the pump which it is.
I have also had the Brake Master Cylinder off to check the seals, I had planned to replace the seals but the seal kit I had was the wrong type 88" (what does this mean?)
There doesn't seem to be any corrosion on the servo where the Master Cyl is attached.
So my query is?
Could the inability to bleed the brakes be due to seals failiure?
or
Is the fault due to the master cylinder itself?
Sorry for the long post, but I have used google exhaustively but to no avail.
So any help would be appreciated.
