Squeeling rear brake issue. Bought a used spawn Yama Jama for my son. The rear brake had a squeal and I assumed a good cleaning would fix it. removed pads and rotor, isopropyl alcohol, rubbed the pads on dry wall paper, the rotors with wet/dry sandpaper. Alcohol and torch cleaned the rotors. Reassembled. Front is great.
Rear has a squeal, but only if I try to lock up the rear. There is good modulation, but requires a sold pull (on hydraulics) to lock up the rear and it squeals first. Super high pitch.
The rear pads did not clean as well as the front. The rear rotor has a little more wear, but still inside the realm of not too worn. Have not looked at the oil line yet.
Could new pads fix this? New rotor? New Oil? All three? Wondering if I am missing something. Never dealt with a rotor I could not clean and get the sound away. Tektro hydraulics Auriga brakes and rotors. Generic pads on there.

Iso the living shit out of your rotors and calipers. Check for hyraulic fluid leaks. Install new pads. Readjust your caliper (loosen attachment bolts, realign caliper)

Sure sounds like contaminated pads. Not unusual at all for the pad cooking process to fail. New pads, and clean the rotor again with alcohol before installing said pads.

Does cleaning pads with iso and then sanding them down a bit work? I had a caliper leak oil all over pads and rotor on my last trip. I put on spare brake and new pads/rotor at the time, but would like to renew the oiled pads/rotor since both were pretty new.
I think the caliper (deore) may be a lost cause though I may be able to combine with another brakeset (xt) that had a failed hose to make one functional set.

Mine got so bad recently that I managed to snap the bolt (connecting the left side arm to the strap assembly). Didn't even have a wrench on it, I was just ratcheting down the arms to hold a bike when it snapped. 1up is sending a replacement, in the meantime I checked the rest of the bolts and made sure they were OK. Loosening the nut until the bolt spins seems sufficient.

I've had decent luck cooking the fluid off the pads. Lots of ways to do it (torch, gas stove burner, douse with alcohol and ignite), just be careful not to get it so hot that the material separates from the metal. They're gonna feel like shit for a bit afterwards. Rubbing some dirt on the pads and rotor has always helped. :shrug:

If your heater or a hot pipe is close to where you want it, it shouldn't be too terrible. And with the magic of shark bite fittings it's probably an easy afternoon task.
And it's so worth it. I've only gotten to experience the magic of a heated rinse station once, but after a disgusting PNW day it was incredibly worth it. And you can rinse all your gear and your body off comfortably as well, which saves on aggravation with significant others when you track filthy gear into the house and throw it in their nice washing machine.

Or just get a hand pump pressure sprayer and fill it with hot water for like $20.

In the winter I drop this into a bucket of hot water.
Works a charm when I don't swing by the hot-water car wash.

Shimano 12 speed cranks - or, more specifically, the tool to install the lockring for the direct mount chainring - is that the same as the tool for the threaded bottom bracket? Looks pretty damn close, but saw a bottom bracket tool measured at 4.2cm and a chainring lockring tool claiming 41mm. Compatible, or is Shimano really fucking with people like that?

Different tool. Lockring uses Shimano TL-FC41 tool or equivalent.

Same pattern but good luck getting anything other than the DM specific tool to grip the tiny recesses. LRT-4 is the Park tool.

Feeling impatient, I said screw it, went for the monkey wrench. Seems to have worked, obviously not torqued to spec, but it does have the spring loaded washer deally so I'm feeling confident. Now, about those two spacers that come with the cranks. Optional? It seems with the spacers the non drive crank is coming up a bit short on contact with the spindle, but without the spindle will extend a bit past the crank. Use one? Which side? Also, since I got rid of my last pair of shimano cranks a few years ago, I "misplaced" the preload tool. Any ideas better than just giving it a few love taps with a mallet and calling it good?

No one local had the shimano tool in stock so I ordered this one on amazon - https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1
I already had something that worked on the BB, which interestingly works on the outer splines of this tool as well.
