Okay so TDLR version: I changed out my left rear rotor as the original was chewed up due to PO neglecting the brake pads & the caliper piston was full on metal-on-metal. The right side rotor seems fine, no grooves no damage, the pads never wore through. So I only opted to change the one side. I have heard this is not preferred because it can cause uneven braking, but i've also heard people say that it is fine, that the pads will eventually wear in and seat where they should be on both sides and its no problem.
My 80 is a HDJ81 with those stupid expensive one-of-a-kind rear rotors that are like $300 a pop, so I really didn't want to have to shell out $$ for both sides if i didnt have to.
Yesterday I went for a drive (about 400 km, out of town and back) and i noticed my wheel with the new rotor was considerably hotter than the rest. Is this normal for a new rotor? I know its can't be the caliper seizing because I replaced that part last fall. *edit: should point out that there was no burning brake smell that i could detect either*
The thickness of the new rotor is a few mm more than the one i replaced, presumably due to the old one having a bunch of material worn down from it. I put new pads on both sides in the rear when I changed rotor.
The other confounding factor is this:
I tried to do this job earlier last year, and while trying to get the rotor off I didn't realize I had to back off the ebrake so I accidentally mangled some stuff in the ebrake mechanism. I had a couple of springs come loose and were just tumbling around in there. I then realized i should probably order new pads before changing the rotor so I just slapped everything back together as it was, deciding that I didnt need a functional ebrake for the time being anyway.
This time when i successfully pulled the rotor, I found the 2 loose springs - i do not know what they're called - but they held the 2 sides of the brake shoes (i guess?) in place via a small pin and 2 spring plates. {see photo attached}. unfortunately one of the pins had fallen out and is gone. So i only reassembled the one side, thinking that it would be fine considering i've been driving for months with the ebrake not in working order anyway. Now I'm wondering if only having one spring in place is causing the parking brake to drag unevenly on the rotor, causing the heat?
When taking moderate speed (30-50km) right hand turns, I hear an oscillating scraping sound coming from my rear left wheel. It doesn't happen when braking normally. I do not believe it matters if im pressing the brake or not while in the right hand turn. I'm wondering if this sound is coming from the parking brake? The parking brake is pretty weak currently, it only engages when pulled all the way to the end. and I tried driving in a straight line with the ebrake engaged and it doesnt make this noise. So im wondering if this noise and the heat are 2 different issues.
Sorry for the long winded post, i hope it isn't confusing. Mainly im just wondering if i need to shell out $$ for another rear rotor on the right side, or if there are some other considerations im not aware of. Im going on a road trip at the end of next week and i don't wanna be overheating my rotor and cooking my wheel bearings.. currently my last resort is just to put the old grooved rotor and the old pads back on
