91 HDJ81 1HDT. So I've been plagued by stuck brake calipers over the last year or so and now that all 4 have been replaced and about 10k miles put on with out issue it seems that all 4 brakes are dragging to the point of needing low range to move without skyrocketing the EGTS.
I parked it up gave it a look over and everything seems fine so I took it out for another drive thinking it was just one caliper locking up so I could identify it with the IR thermometer. After a lap around the block and a really hard brake peddle I took the temp of each wheel and fronts were dead even at 180F and the rears were 100F & the ambient temp is around 25F.
Possible causes?
1. Master cylinder sticking
2 Brake booster doing things it shouldn't
3. Vac pump also being a bastard
Anyone have a direction they can aim me?
