Working on Brakes (especially Rear Drums) - TJ
 

Hey...I am about to pull my brakes apart due to some persistent brake
fade issues (dry or wet) I've been having with my rear brakes; I want
to make sure everything is ok/fix whatever's wrong with them.

Anyway, I'm going to start scouring the 'Net tonight to look for info
how to work on brakes, diagrams, instructions, etc., especially for
the rear drums (the front discs are more straight-forward from what I
understand, and I'm pretty sure I'll be able to figure out what's
going on with them a little easier).

So, if anyone out there can provide me with any links to instructions
they've found particularly useful in the past, that would be awesome.
Pictures and diagrams are great, too. Bill, if you feel inclined to
put up a link to the appropriate section from the FSM or something,
that'd be awesome too. Also, any tips or suggestions what all I should
do when servicing and checking my brakes (beyond the obvious
inspection and replacement if necessary of the pads...) would be
great!

Thanks everyone.

/Bob

Drum brakes are not that much more complicated than disc brakes. The brake
shoes expand to exert pressure on the inside of the drums, instead of
pinching down on the rotors as what happens in a disc brake. The complexity
is entirely related to positioning the springs and related hardware.

Re: Working on Brakes (especially Rear Drums) - TJ
 

Are you sure you aren't just seeing the effects of a properly working
combination valve?

It acts like an anti lock brake for the rear wheels so they don't lock
up easy if at all. Normally you don't want the rears locking, you can
do 360's faster than you can blink if the rears lock up at speed.

The combination valve stops them from locking until you are almost
stopped even if you really mash the pedal down.

Hi Bob,
Start out by using a good product Bendix or Raybestos:
http://www.raybestos.com/usa/brakepads.htm
A couple of pictures:
http://www.4x4wire.com/jeep/tech/axl...2/DSCN0915.jpg and
http://www.4x4wire.com/jeep/tech/axl...2/DSCN0913.jpg
The tricks I use with drum brakes, is to remove the wheels and
slide them under the frame for a little extra protection in case I jar
it off it's blocks. Usually the drums stick a little to the hub, I
squirt the lugs and center with with WD-40 and hit it with a hammer at
the drum's edge like you were going push it back on and make it ring
like a bell, usually it pop lose, back at you. Rather than the twenty
years I did blowing the asbestos off with air, I've found that a blast
with the garden hose does a much better job of containing the dust and
cleaning the parts you'll use again, then disassemble. As you
disassemble place the parts on the tire rim you have lying beside you so
as they are in the same position as they look on the backing plate, will
help immensely with the different color coded springs on reassemble. If
you heard a metal to metal sound before you started work on the brakes,
then you may have to poke a small screwdriver through the backing plate
to push the ratchet lever back and release the star, and another to back
it off before the drum will come off.
God Bless America, ßill O|||||||O
