After having my front rotors (with ABS) machined about 10 months ago,
they were
'juddering' again. So I have replaced both the rotors and the pads.
Pads are Bendix -
'Titanium Stripe', rotors are slotted. Replaced bearings as well. When
tightening I lightly
used a socket to bed the bearings then backed it off and then hand
tightened.

Problem:-
1/ ABS light is on.
2/ Noise from left wheel.
3/ Sometimes the pedal feels jammed then releases.
4/ Brakes are spongy.
5/ I read on this site about torque settings for the EB bearings, WTF?
6/ I didn't check to see if the sensor rings were on the new rotors.

Questions:-
1/ What is the torque setting for the bearings or where will I find it?
2/ Are the pads rubbing on the wheel to cause the noise?
3/ Why is the pedal jamming?
4/ Should there be slack in the bearing when moving it back and forward
by hand?
5/ Is the piston jamming?
I will take the rotors off tomorrow to check if the sensor ring was
actually supplied.

TIA - Jobbo

Correct steps are:

a) While rotating wheel tighten nut to 23 to 34 Nm to seat
bearing.
b) Loosen nut one half turn.
c) Retighten to 1.5 Nm.
d) Check that wheel rotates freely without any wobble.

Did you lubricate the calliper slide pins with white silicon
grease as you are meant to? If not the slide pins are probably
corroded and jammed.

Thanks for your advice Blue,
I found the problem, I didn't see the plastic/rubber inner seal that
goes in the rotor to cover the inner bearings on the old rotors. I
thought they were grease cups that slide onto the stub axle before you
put the inner bearings on. They were spacing the rotors away from the
inner bearings and allowing free play of the bearings. I got new ones
and put them in correctly, hand tightened and made sure the rotors
rotated freely with no play. Drove the car and then checked for free
play again and everything was fine. The car breaks well and straight.

Thanks again for your good advice.
