Hey gang.
Any tips for methods of checking for front brake rotor warpage?
Im noticing some pulsing through the lever at low speeds.
I have a dial gauge with a magnetic base but cant figure a way of measuring the rotating disk and ensuring its spinning true on its axis relative to the dial gauge.
more info:
I recently (6 months ago) purchased some new floating disks for my 1100 front end. I got the cheapest I could find and they were Chinese aftermarket jobs. Also got some cheap Chinese pads
I think I may have been a tad over enthusiastic during the bedding in phase and caused one to warp.
Today I removed and dismantled my front callipers, removed the pistons and cleaned everything. Replaced all the fluid with new stuff.
The new cheap pads needed some filing out of the holes that the mounting pin goes through, as they were not quite lined up properly. Now they slide more freely on the pins.
The pulsing is still there but seems to be significantly less.
Ive used a straight edge to check the rotors for general flatness and couldnt notice any warping. But this is far from an accurate method Id say....
