Passenger brake dragging

[aaronswink]

Ok, first off a little info on the truck. 1991 5.7 tbi, nv3500, rough country 2/4 drop. Put the 1.25 width rotors, new pads, new calipers both sides on the front. 2002 suburban master cylinder(brake pedal feels way better) I bled the fronts and now every time I hit the brakes the passenger side caliper holds and won’t release all the way. Could this be because of master or am I missing something?? Please help if you can

I could be way off on this, cause I really don’t know, but often on this forum I hear those who do seem to know mention how these brake systems are “systems” and when you start mixing other parts into the system it doesn’t always work.

Guy on here told me it’s a great upgrade. What is an rpo? And where do I find it?

Send or pm me your vin #. I'll be able to tell. Actually, I may not be able to tell being a 91. Take a picture of sticker in glove box.

passenger side? Id say your hose, your banjo bolt, rust in the system, or the caliper lube/hardware fitment are most at play. I suppose it could be something upstream but that seems like it would affect more than just than front right. I would say go over your work and verify your hardware and service. Using a petrolum grease on the slide pins is a good way to accidently seize rubber boots(if those calipers have that)

Im going to grease slide pins now, I used banjo bolt and new crush washers to when putting on, also when I hit brakes it dives left, not as bad now that new pads on left an new master but going to re check everything before swapping back masters

Just checked and you have JB3 brakes. Understand why you were looking to upgrade.
