There are no recalls for my truck. When I was first checking the vacuum I also looked at the brake pressure and it was 2500 to 3000 psi the first couple of pumps. I have not been able to it to that level again and it never goes above 1500 on a very hard stop.

My 2018 GMC Sierra doesn’t stop as good I think it should. My 15 Silverado stoped better. I’ve tried better pads didn’t help. I installed power stop kit on all 4 corners and no improvement. I had it to the dealership they just blew me off. I’ve checked the vacuum pump output lowest it falls in 9 inches of vacuum. My next thing is do any of the techs on here know what the brake psi output is supposed to be.
