So since putting on the 2/3 drop Saturday, been experiencing a weird random brake related issue. At least for the McGaughy's drop spindles you have to trim the brake backing plate some in order for the caliper/caliper bracket to bolt back up. I had kind of forgotten this and wasn't well prepared by the time I had it all torn apart and needed to trim them, so I had to do it with a pair of snips. Needless to say it was a bit of a hack job, but I got it done. The driver's side plate got a little bent up while doing this, but there was adequate clearance between it and the rotor after reassembly.
What it's doing is at slow speeds, light braking, and only when mildly turning (seems to happen more when turning right), I get a quick vibrating/pulsing of the pedal. Almost like the ABS/wheel speed sensor is freaking out causing the ABS to kick in. Since the hubs had to be removed to install the spindles, I did remove the wheel speed sensors from the hubs, and then reinstall, but don't see how that could have impacted anything.
Kind of at a loss at the moment. I ordered two new backing plates that I'll cleanly trim and install this coming weekend, and also have good look around everything up front, but I'm struggling to come up with what might be causing it.
Any ideas or similar experiences?
