Outer Limits 4x4 Board

I can't believe I need to ask, this is embarrasing.
I have on a number of occasions done the disk brakes on both my wife's old Magna, and on the Subaru I made her buy to remove the shame of driving around in a Magna.
But I've never done either the brakes, or even had to change the tyre on a 4wd with locking hubs.
The fronts on my Patrol has AVM hubs. Is it still just as simple as taking the wheel off, or is there something more complex involved when there are hubs to be dealt with?

Also, any idea on the grey import high roof Patrols (89 Diesel Ti model GQ) rear brakes? I haven't got the car here at work, so can't go and see if they are disk or drum.

It's also an auto, so does require the odd bit of brake on descents, so any recommendations on the best pads to use for off-road that won't fade etc if they need to be used a touch more than normal on a long downhill?

Thanks in advance

I know nuffink about your truck, but mine is no different from any other car front discs I've done.
How they are held into calipers varies, but take off wheel and change pads.
It will possibly be very dirty
May need a caliper kit too, just make sure everything is free running and not siezed.

OK, thanks. Just going through the job in my head while I was at work (you don't expect me to think about work at work do you?) and it suddenly dawned on me I had no idea what happens with the hubs. If they come off with the wheel, or the wheel comes off around them, or what?
So thought I'd ask so that I could decide whether to run past the shops and buy some pads on the way home (when my wife stops running around in my car)

it just about all the same, take off wheel nuts take off wheel, your might be double pistion or single pistion on the brake calibar on the front you will have to see, i find bendex is ok iv also use silverline from repco,

undo the bolt pull iut out lift up ya calibar take the 2 bit of steel remebering how they came out use a clamp to push piston back in a tad pull out the old in wiht new do it up same way as ya undone it ,
bleed the brakes

Wheel comes off around hubs. You dont have to touch the hubs at all when doing pads.
My Ti had rear discs so I guess yours will too. They are a snap to change pads. You'll be done in an hour.

EDIT: dont use Silverline pads. IME they suck balls.

WTF? bleed the brakes when doing disc pads?

you can put a dob of silastic on the back of the pad before you put it in and it stops it squeeling.

yes thats right, every time i change my front pads and back
i bleed out the old crapy brake flu and pump in the new stuff

Thats a good idea to change the fluid... but it is not bleeding as such, as in bleeding to remove air... Its only to renew the fluid.
I think brake fluid is ont of the most neglected things in a car besides gearbox oil... lol Most people never look at them let alone change them

When the old pads are out, check how easily the caliper slides in and out. Mine were seized with crap leading to premature wear of the outside pad, increased fuel economy, stuffed disc and a stuffed diff seal (presume heat...).

I'm not sure how often the capiler slides need to be greased (or even what to grease them with - I used a small amount of hi-temp grease), but it's worth checking whilst you've got it apart.

There is a caliper lube you can get in a tube which is what I use to free my calipers up.

The only difference I can see between this product & hi-temp greese is the colour though. LOL
