lsd not functioning properly? or is it a seizing caliper?

[vinnY]

okay so story goes

1. jacked up the front of the car
2. removed wheels
3. started car and ran it through the gears through 1.5-5krpm
no wobbles evident
4. applied throttle and brakes at the same time, felt a little wobble and let go of the brakes(process done in about 10 seconds)
5. left it in second and let it idle and got out of the car

get out to see my driver side hub not moving at all whilst the passenger side was spinning happily
tried to spin the hub with my foot and hand and needless to say it was fairly difficult to move
so i turned the car off and tried to move it again, still pretty tough
could this be the cause of my odd brake wear (http://www.ozhonda.com/forum/showthread.php?t=118457&highlight=brake+wear)?

heres the kicker, got a dc2r gearbox which is lsd equipped
so as far as i know, it would be impossible for only one side to spin

so what's everyones thoughts? one or the other? or both?
whilst the car still drives fine(and have actually been doing so for over a year) it's still something i'd like to fix asap

So have you checked the driver's side caliper?

[bennjamin]

piston seized/seizing - fix it up

[vinnY]

not sure how to check the seized caliper to be honest
when i changed my pads it did go back into the caliper itself
might just swap it out with a spare caliper from a mate
will reporting my findings soon

Vin,
I don't think you have a problem with your diff, but you might find that the sliders on your calipers are not moving as freely as they should. This will cause the sticky wheel and abnormal pad wear. It is the outside pad that is wearing, Yes?
The standard LSD is a torsen type or torque biasing dfferential. In order for it to engage and send drive to BOTH wheels it needs to sense load on both of the wheels, this is what generates the torque required for lock up to occur. If one wheel or both is freewheeling without load, either, in the air due to jumping kerbs or up on stands, (as is your case) then no torque can be generated, and the differential will remain open (unlocked). This is the opposite to a clutch pack differential that is default to lock engagement and torque between the axles causes some slip to occur.

ah i sees

well i actually pulled out, cleaned and relubed up the slider pins a couple weeks ago and they appeared okay
no score marks on the pin or caliper bracket and when i plunged them they appeared to move freely for the entire length of the pin too

[bennjamin]

take the pads out of questionable caliper - get someone to apply light pressure to brakes and see if there is relevant movement to the piston. IE back and forth

[aaronng]

Emphasis on "light". Too much pressure and the piston will fall out of the caliper.

could just whack a block of wood there to stop that from happening can't i?
