I suspect my rear hubs are full of mud from the swamp as one minute the handbrake applied as normal, then the next time it goes stiff only half way up.

Can anyone remind me how easy it is to remove the covers?

Nuts off

Wheels off

Spacers off

Blank.. :rolleyes:

Hubs off
 
Check your h/brake cables as well as they could be caked in mud stopping them working correctly but to get the drums off jack up the back end & put on stands:thumb2 take wheels off & use 2x M8 bolts I think it is to screw into the 2 holes in the drum to pull it off then clean & adjust brakes if needed:thumbs
 
Two threaded m10 holes in front of brake drum screw two bolts in evenly and it will start sliding the drum off the hub. Inspect as pernormal.... do not touch the brake pedal with the drum off or you fire the pistons clean out of the cylinder.

Take the tension right off the hand brake lever adjustment and put the lever in the down position, next get a flat head screw driver and turn the small adjusment sproket on the preset rod between the two brake pads untill it is just touching the drum as you slide it back over the brake shoes.

You might aswell adjust them right up if ya going to pull them to bits.

Handbrake operation

This happened to me years ago on a Vauxhall FB series Victor. I had been off roading in Wales on a Forrestry Commision Road - turned out to be a broken rear spring that allowed the wheel on that side to move backwards taking up the handbrake adjustments. Had to disconnect the handbrake completely to get her home for new rear springs !
 
Did mine yesterday.
1 slightly loosen all 12 rear wheel nuts while vehicle is on the ground
2 Chock front wheels
3 Jack up rear Diff, place two axle stands under axle, one each side
4 using a 10mm deep socket, loosen the hand brake adjuster nut by putting handbrake on, and moving aside the plastic piece under the handbrake to expose the nylock nut. Undo about 5 or 6 complete turns, then handbrake off.
5 remove rear wheels
6 using 2 x M8 bolts in the threaded holes in the drum, tighten until the drum starts to move, then slacken both and hit the drum with your fist, or rubber mallet, and you should hear the brake linings drop back, you might need to do this two or three times.
7 Slide drum off
8 clean linings and drum with brake cleaner
9 inspect components for leaks
10 adjust auto adjusters one click at a time, but place drum over after each adjustment to check.

Caution
Avoid beathing the dust
Only remove one drum at a time, as when you place the drum back, you might want to use the handbrake or foot brake to centralise the shoes after adjustment or replacement, and you don't want to wreck the slave cylinders by popping the pistons and covering the linings in brake fluid...:doh

When you are happy with the auto adjusters, replace wheels, tighten wheel nuts then go to hand brake adjusting nut and tighten, what I do is note when the shoes start to bind on one click of the handbrake, when rotating the rear wheel to check for binding, both wheels will turn in the same direction, due to the LSD and the wheel is quite stiff, but you can detect when the brakes are just binding.
When happy with this, remove axle stands and jack, then tighten the wheel nuts using a torque wrench.

Time to do this task... 30 mins to an hour...

DO NOT attempt any work on the braking system unless you have the necessary experience, the correct tools and safety gear.
ALEX... I know you have axle stands.... so use them...:augie

Go for a test drive, which doesn't use much braking, and check the drums for excessive heat, due to any binding, and be prepared to slacken the handbrake adjusting nut.

An alternative, is to drive to Ricks via a suitable retailer to purchase ia bottle of Malt whisky.:thumb2

I remember this from ricks somewhat, I don't remember using those m8 bolts to slide off the hubs though, just a mallet if I remember.

Also I have the facelift model and the auto adjusters actually work :p

All I'm gonna do it remove the mud I think :eek:

RICKkkkkkkkkkkkkkkkkk!! :lol:lol:thumbs
 
RICKkkkkkkkkkkkkkkkkk!! :lol:lol:thumbs

Well... if Alex is doing it... What can possibly go wrong? :doh:doh

:lol:lol
Assuming he does it right... when he checks it, it's still as bad as before...
what else..?
 
All is ok and done, lots of horrid sludge removed from inside the hubs, this job was made much more difficult by the fact I have wheel spacers, the bolts must be perfectly inline for the spacer to realign otherwise it will not lay against the hub.. Still all done now :thumb2

Considering these are only 8 months old (shoes and cylinder) they are looking pretty sorry for themselves :eek:

Rick did mention the rears will wear out faster than the front shoes :thumb2
The truck is certainly not binding as I roll easily on any slant

All these pics are after I removed the sludge that I could... Not long left on those rear shoes :eek:
