LSPV Issue...thoughts?

[reetzy]

Hey all. Just replaced all front and rear pads, drums and rotors and was in the process of adjusting the LSPV and cannot get it to lock the rear wheels up. I have had the rear off the ground (jacked under axle) in first gear idling and cannot get it to stall the engine when i apply the brakes, anyone had this before? Two things i see that could be the fault.

1. LSPV is faulty
2. ABS system stopping it from doing this (although it should?)

Note: All the brakes are bleed correctly with no air at all in the systems, rear brakes are adjusted correctly. Thoughts?

Also anyone have a seal kit part number for the LSPV or a new part number?

Will the handbrake stall it? May just need bedding in.

Nope handbrake wont either. New pads new drums all installed correctly.Hand brake has about 5 to 7 clicks and its very firm.

I just did my rears the other day and it took a coupd days of driving before the handbrake worked properly.

Still the brakes should be able to stall the vehicle i would have thought.

Anyone got a seal kit for one before or replaced it?

Tried adjusting the valve all the way to see if it changes?

I have the extended rod and its maxed out. Next weekend I will tie it up and see if that makes a difference.

if the hand brake don't work either then it probably is not a hydraulics problem especially if you have a hard pedal. Did you clean the inhibitor off the new drums before you fitted them?

If the hand brake doesn't apply enough pressure neither will the wheel cylinder, and yes I would imagine the ABS would get involved, try removing the ABS fuse but only when it is on stands, do not road test it like that.

Hi Marty. Yep removed all the inhibitor off. This weekend I will try and bed the rear shoes in more and have a play with the valve to ensure it is working correctly.

If the wheels r off the ground the valve wouldn't send pressure to the rear. Correct or not

[cooganstein]

With the suspension at full extension, I forgot to add

With the wheels off the ground the lever is pulled all the way down - very minimal pressure would be going to the rear correct.

Jacked up under diff housing is the same as being on the ground.
