Here's some real world guys who had the issue and fixed it and then had to argue with cooper about it

There are hundreds of articles out there about a pedal that goes to the floor and almost every one of them recommends checkingthe wheel bearings.

I recall it looking more like this....
Which of the following conditions can cause brake pedal fade?
a. Seized wheel cylinder piston
check
b. Brake drum machined beyond its limit
c. Leakage past the master cylinder cups
d. Air in the hydraulic system

This question has the word EXCEPT. For this question, look for the choice that could NOT cause the described situation. Read the entire question carefully before choosing your answer. All of these would cause a low brake pedal, EXCEPT:
a. Brake adjustment
b. Loose wheel bearing
c. Low brake fluid
check
d. Seized caliper piston

The complaint was a petal dropping nearly to the floor to where he removed the drums expecting to see leaking wheel cylinders. Spongy was not the complaint.

Didn't watch. I think this proves your point.. You win,

but I'll bet you a Bourbon County Stout that it is not a wheel bearing... Shipped UPS.

Low spongy peDal describes a peDal that is dropping nearly to the floor...

Which, as ASE explains, could be caused by a faulty wheel bearing

I already explained that it's most likely not a wheel bearing, in fact i wouldn't have even mentioned it if I hadn't known he had replaced them recently. Improper torque will make them fail quickly.

Give it up man. He clearly can't get it through his fat head that on this vehicle the bearing is part of the entire hub assembly even though there are pictures that show it as such.

It's a for profit study exam. Why do you think a warped rotor or a bent hub was not on the list? They effectively create the same condition of the caliper piston being forced back into the housing. An out of round brake drum will do the same thing pressing the brake shoes back into the wheel cylinder.

Like the ASE test question addressing that a VD issue CAN be caused by moisture in top of a battery question...ya, It could but...

The adjuster and e brake rod won't let an out of round drum push in a wheel cylinder.


Wrong again.


And a warped rotor or bent hub won't move near as much as a wheel bearing.

It doesn't come into play when testing in a stationary position. Is you petal dropping lower when you're driving then when sitting still???

Do you have an E brake that works? What happens when you apply it and then apply the brakes???

Than.


It should be than.

And its pedal. With a ****ing d

LMAO

Anyway, back to the post that started it all, is there a way to troubleshoot to determine which of these could be causing the problem?

I replaced the wheel cylinders and bled the system but still the same problem. Also checked the hubs just for fun and everything is tight up front.
