I’ve been putting off doing the smart’s brakes since I got that Yamaha U7E. The reason for it is because I remembered that my right wheel’s rotor still had its locating/locking bolt. With me needing to drive 5 hours down to get to the start of the Gambler 500, I can’t wait any longer.
When I did my brakes in 2017, the left rotor’s bolt was seized despite use of anti-seize back when I did my brakes in 2015. Not even my mechanic friend’s impact could break it loose. He ended up having to drill through the bolt. We were able to get the right side off in 2017 and for whatever insane reason, I decided to reinstall it.
Well guess what was seized last night? Despite sitting in PB Blaster for over a day, the bolt wouldn’t budge and the impact I had on loan nearly instantly rounded out the head, much like the impact from 2017 did to the left side. I take it these bolts don’t age well. At any rate, my Harbor Fright tools made short work of the bolt and reduced it to metal dust in just a few minutes.
It took me four hours to do my front brakes, two of those hours were spent fumbling around with the darn bolt trying to get it off without doing the nuclear option. Add another hour for me doing it wrong at the start.
How bad were the right pads? The inner had maybe a thousand miles left in it. The outer was close to practically disintegrating. Outer right pad wear is a common problem in smarts from brand new, so it’s just the nature of the beast.
The rotor was badly scored from the outer pad, but it actually performed better than the rotors I replaced in 2017 did, where they were just big chunks of rust.
The left pads had maybe 3-5k left in them.
