Brake job?

[ktcnyc]

Hi Folks, so while returning from Maine and on the way to a visit in the Berkshire Mts. (hills I thought) I decided to take a back road that looked
good on my old Rand mcNally ... turned into 20 miles of a crazy roller coaster with no escape culminating in a long plunge with a truck escape lane,
hard left and complete stop at a country road intersection.
-last truck escape lane I saw was in the Sierra Nevadas! Fortunately a PO installed rear disks in 2014. I found a place to pull over to let the brakes
cool off
(yes I used a lot of lower gears)
Upon a restart and luckily a new road my right front wheel developed a loud squeak-squeak. I assume that's a brake pad warning.
Like a car I also assume the front brakes do most of the stopping work.
Should I assume I need new rotors along with pads up front?

You should measure the thickness first.
To replace the rotor takes some doing as you need to undo the bearings,
which require a special puller.
Adjust the rear brakes by backing up and slamming it on and forward few
times to adjust it with the auto adjust.

Kevin,

If you had asked, I could have told you. That was a lot of the ground that I used to enjoy.

Now, if what you are hearing is a brake warning, that it has cut into the disk is not a given. Better hope it has not. The TZE knuckle are like some
Hondas with the disc bolted to the back side of the hub flange. They have to be pulled apart to get the disc out.

Whether the front are doing most of the stopping is dependent on how the brakes are balanced. Without knowing what was put on and how, we can't tell
you for sure. What I can tell you is to get it home and get the front wheels off, bet I bet that is your plan right now.

Oh, and just to mention, yes there are real mountains in the east. Maybe not as tall as some in the west, but real none the less.

Matt

If the rotors are not scored to badly, some of us have used a "Bear 1460 brake rotor service system" which allows the grinding of rotors while on the
vehicle. We did this several years ago at a work rally and did a very acceptable job. Here is a link.

Jim he states 6 wheel disc so backing up not useful.
You can check pad thickness with a simple visual inspection. My big concern is always wheel bearing grease overtemp. If you check Mobil 1 specs even
it is only rated to 305F.
