Hi,

I'm wandering whate GM is useing for the rear caliper on late model trucks. I'v seen pics put not enough detail. Are they single/duale piston?
do they have a built in mechanical parking break?
Has anyonr had to buy one yet, how much?

any info would be great, Thanks

Russ

All else fails call dealer for specs.......:D

I'd be interested in knowing too since I'm installing a HD-D44 brake setup on my rear dana 60!!! At the moment I'd be without emergency brakes.
