Brake Squeal

[Norm Peterson]

One track day with roughly 50% pad remaining and squealing loud just before coming to a stop. Annoying as hell .What is more concerning is that when hard on the brakes, daily driving, the car struggles to stop and ABS kicks big time. No soft pedal feel, but rotors feel liked they are glazed.

When you're easing off brake pedal pressure is when squealing is most likely to occur. Less pressure between the pads and the rotor makes it easier for the vibrations to show up.

The ABS activity suggests that the front pads did get glazed but the rears did not. I am assuming that it's the rears that are going into ABS.

35 minutes of blah, blah, blah. Guy gives me a headache. Thanks for posting it nevertheless. :cheers:

It did have some useful information, particularly the part about wheel cleaners (that I won't start using).

But I do question the idea of letting the Locktite Blue even begin to set up. Installation torque is not an end result, it's an indirect indication of the joint having the proper amount of clamping force. Losing a few ft*lbs to extra resistance from the Locktite setting up might not be the way to go here.

He really did several things here, each of which could have been the subject of a separate little maintenance tip. Google "Andrew Markel Maintenance Minute" for what I'm getting at (in fairness, Andrew's tips are primarily intended for technicians working at independent shops and are scripted with that in mind). Scripted, as opposed to a "stream of consciousness" approach.

You mean techs like what works at Ford dealerships? :lol:

I've used wheel cleaners on all my vehicles for years and have never had a problem with brake squeal.....oh, wait! There was that 67 LTD I drove in the Colorado mountains as a young buck back in the day before God imbued me with all the knowledge of the universe and I wore the brakes down to bare metal the first day. But then again, that was more of a grinding noise vs a squeal.

The guy in the video reminds me of nutnfancy.

Not just dealership techs, maybe mainly not those guys at all. More for people working in the chain store service departments, regional outfits, and independent shops.

There may be some difference between sliding calipers with one or two pistons on one side only and the more 'open' opposed-piston Brembo designs with their big flat springs.

I've never really trusted the use of chemicals to clean wheels, and that's without stopping to think where that stuff might end up after rinsing it off the wheels. Just one more reason now to not get started with it.

I used to use wheel cleaners on my old car but now I don't. Those chemicals are HASH despite how "safe" they are for even painted wheels. Soap and water with a brush is good enough for me.

Ditto, stopped using them several years ago and remove wheels at least once a year to do a thorough cleaning. Use soap and water with brush during a normal wash. We're lucky to have black wheels (and satin at that) as my 991 had silver and rims were filthy 20 miles after washing...
