Technically the bolts are one time use.

Stoptech is cheaper, consumables are cheaper and also they include the bolts FWIW...
Cheaper to own across the board.

Mine are Brembs. Even just glancing at them cost me $$

Fug it. What's another $60 bux gonna do in the grand scheme of things. Should I overhaul the parking brakes. NOT that it really was on my honey to do list radar.

I have not really looked at how many miles on pads or discs. Technically I could go a maybe 6 months more on the fronts. I dunno. Brembo calls for 1MM of wear. Stoptech calls for 2mm. I would day I would get 4 years of use - eh maybe 40K miles on them as a WAG.

In my case, it is super extra-ordinary. I don't know root cause as none of the rotor/hat bolts are broken/ sheared off. I suspect a bolt came loose somehow which telegraphed to all the bolts on the hat to be stressed/loose. Right now, one rotor has complete slop against the rotor hat on all 10 holes. I can literally move the rotor N/S/E/W with it on the hat. I don't drive the truck much. But I picked up on the noise when I did. It's pretty bad. When I took the wheel off off to take the rotor off to inspect, the holes have been elongated, and in 1 or 2 areas where the bolt from disc mates to the hat, there is very very little meat left...
