You can buy plastic clamps made for pinching hoses.
It is a good idea because when I did my '91 at 100,000, on the right rear
wheel, I opened the bleed screw, compressed the piston, and then realized
that the bleed screw was blocked. Everything has been OK, probably because
the rears are a long way from the valves. Make sure fluid is coming out the
bleed screw as you push the piston in.
In flushing the system, the bigger danger is running the tank dry. I tried
bleeding with the ignition completely off, me opening the bleeder and my
wife standing on the pedal. What a joke. So I had her turn the key to on -
which on the '91 turns on the pump that pressurizes the system. When she
stepped on the pedal I had a solid and rapid flow out the bleeder. Luckily
I had used a round plate and a spout that screws to the fluid
container–which came with my hand vacuum pump. You invert the brake fluid
container over the opening in the tank, through the plate. The spout is
about the right length to fill the tank without overflowing. As brake fluid
was pumped out the bleeder, the container of brake fluid rapidly emptied.-----Original Message-----

I should have read this note before seding the previous reply. Can I ask,
how do you clamp the brake line?

This sounds like the problem that will sometimes occur with the Teves system
when the front brake pads are changed improperly. With the Teves system it
is very important to clamp the brake line at the caliper and then to open
the bleed screw before pushing the brake piston back. This way any dirt or
grit in the brake fluid is expelled from the system rather than being pushed
upstream into the ABS valving. The ABS valving cycles at a high rate (6-8
times per second) and the valves are very precisely made; any small bit of
grit or dirt in the valving can cause this to occur.
If the pull is very violent when it occurs, IMO the problem described is the
most likely cause.
Some people have reported success in fixing this by flushing a large amount
of brake fluid through the ABS valving; others have had to replace or repair
the ABS block to fix this. Jaguar does have a repair kit for the valving
IIRC, though none of these pieces are cheap.

my 91 xj6 brakes are pulling bad. When I hit the brake
hard it pulls violently to the left. If I put slight
pressure on the pedal then brake hard, it works just
fine.
