UPDATED: Received a 50% refund and I justify that since they did a ton of labor. I would come again seeing all of the other great experiences people had.
I wish I could give them a better review because they tried to fix the issue I caused but ended up causing an issue themselves. I did one caliper on my 19 Silverado and forgot to put the truck into service mode, caused a bunch of dash lights and 43mph limp mode, so I brought my truck to Rayco.
They had it for 2 weeks. They installed the other caliper (passenger rear), bled the system, cleared the codes, but the dash lights would come back as soon as they pressed the brake pedal. They had a GM tech come in to relearn the brakes which was a 150-dollar charge that I paid, even though they offered to split it, because they said the problem was fixed. Well, when I turned the truck off and back on, every light came back. I called them up and they said they'd take the truck back. They worked on it for another week and eventually told me they can't do it.
Brought it to Vara Chevrolet and it ended up being a bent crush washer on the passenger rear caliper that seals the brake line to the caliper that they over torqued. I'm sure it was just a onetime mistake, but a torque wrench would've made all of this go away.
