Need brake rotor advice please
My front rotor (r) is discolored. Last year I mounted new brake pads on my 2002 KRS. Didn't need to, as it turned out, but I thought they had worn enough. New ones went in ok but when I remounted the front wheel there was friction from the ride side pads when I free-wheeled the front. I thought the pads just needed to be seated so that's what I did. Friction remained so I took her for a 100 mile ride and ran the front brakes hard from time to time. The right front rotor got HOT--the left front was only warm. Now I notice some discoloration on the right rotor and a shuddering (mild) during front braking--at lower speeds. I assume (rightly or wrongly) that I have heat-warped the rotor slightly. My questions:
1. Is is possible to tell if the rotor is distorted when I remove it--can you test it somehow?
2. Can the rotor be milled to reduce warping if it is mild?
3. How much can we remove from our rotors during the grinding/milling process?
4. Should I swallow the price of new rotors?
I took every precaution when remounting the front wheel--I've done it 4 other times for new rubber--bouncing the front shocks etc. It does seem the axle spacer will go on either way, but I can't remember the correct way and I don't see how it could make a difference anyway.
Self-inflicted damage for an unnecessary wrenching exercise. I am suitably humbled and would appreciate any advice anyone has on my above queries. My nearest dealer is 400 miles away and it's winter here (central Canada) so I have to get this right myself.
Thanks in advance.
