1990 Trooper 2.8 dragging rear parking brake??

Postby Getsducks » Thu May 18, 2017 12:52 am

Howdy fellas,

I've just test drived one new rear R caliper and new pads rear both sides.
Lubed up slider pins with silicone based right stuff (can't remember name),
It was a btch getting piston on left side back in position (I know it's a twister),
after removing and draining brake fluid 5 more turns and wolla!

Drove good for about ten miles with little heat radiating thru wheels, but the backs are not cool like the fronts?!?? Luke warm at best..

Checked parking brake cables mid way and both had 1/2" - 3/8's travel to fully reset to release. Still plenty of slack in the cables underneath once P brake released...

Any tips out there for what I might have missed??

Thanks for any advice.

P.S. I've got a fair trip to make tomorrow and I'm afraid of going backwards on this one.

Cheers,

Sean

They are a major hassle. To check the caliper itself remove the cable and actuate by hand with vice grips. Make sure they completly retract by themselves. If they do then the cable is likely hung up in the sharp bend under the axle. It's very common Jerry has new ones I believe.

Hmmm.
Passenger cable is free moving (new). Drivers side a little less (original).
When I said "both had 1/2" - 3/8's travel to fully reset" I meant both parking brake return springs.
I'll back off the P brake cable tensioner maybe?


Thanks
