1997 Defender 300 tdi.
There appears to be no servo assistance so that you need to almost bend the brake pedal to stop.
I have renewed all the pistons and seals in the calipers, all the brake lines, the vacuum pump and the brake servo. The pedal is very firm and is without air in the system.
The brakes don't bind and there are no leaks.
Disconnecting the vacuum pipe where it enters the brake servo gives as much suction as my friends same year defender (which has good brakes) but I notice that depressing my brake pedal gives no "air" noises like my friends defender. Putting the pipe onto my tongue is sore but not panic inducing! Having the engine running does however make the pedal more squidgy but the stopping power is very poor. With the engine off and pushing the pedal down and then starting the engine the pedal does not go down at all.
Do you think I have bought a faulty new brake servo to replace a faulty servo, or is my Britpart vacuum pump as poor quality as some people would suggest?
Off to do a nightshift shortly but will look back tomorrow. Thanks for any replies meanwhile!
