Preventing and removing brake pad deposits on rotors? Topic is solved

[MoVolvos]

How can they clean up a rotor, hone the insides, install new seals , bleeders, test , shop , wholesale , and then retail for $40?

By externalizing the cost through subsidized production. That way the cost is spread across a multitude of people other then the end user.

Insures that the incorporated persons with the deepest pockets and best attorneys wins the game. The little guy get booted out of the game because he cannot afford an attorney that can navigate the bureaucratic regulations and get his production subsidized.

Subsidized as Big Gov giving money to farmers?

I'm pleased to announce that the Flex-Hone For Rotors removed the pad deposits on my rotors, eliminating the loud thudding when I applied the brakes. You need access to a machine shop lathe and a drill to complete this work yourself. See the brief usage instructions for more info.

As a refresher, the deposits were created when the car sat for a week with some rainy days. The pads stuck lightly to the rotors so when I first moved the car, I heard them break free. From then on, braking caused loud thuds as the deposit on the rotor passed under the clamping pad. I drove for two months and the deposit never went away.

In my case, the deposit was on the rear left rotor inner face. The deposits (marked in pink) felt slightly rough to the touch. Though the Flex-Hone manufacturer doesn't recommend it, I ran the hone against each deposit before putting it on the lathe. This generated a lot of brown dust, made it look like the deposits were all rust pitting, and made them much more rough. I then followed the manufacturer's directions by applying the hone with the rotor spinning on the lathe. This made the rotor perfectly smooth and almost entirely removed the rust pitting. I'm doing something wrong and not achieving the advertised surface finish.

Pad deposits and excessive rotor rust have happened to me many times in the past. The Flex-Hone For Rotors provides a way to remove this damage by removing essentially no material. It's easier than turning the rotors and cheaper than replacing them, especially if it happens often. Find a Makerspace near you with a machine shop lathe you can use.

And yes, there's an underlying problem which caused the pad deposit. I think the caliper held the pad too close to the rotors. I am replacing the calipers, but will dissect the old ones to see if piston corrosion was the cause. When these deposits form again, I'm ready to hone them away.

Parts are not that expensive at the source. This guy says 10 minutes so how much faster in a basement of the Nike factory.



Replacing only seals. This guy has good videos.

I’ve sent mine in for rebuild. Haven’t heard back yet
