Hi all, I'm in the process of fitting new discs and pads to the front of my '96 disco and thought I would share the experience with you as a cautionary tale for anyone thinking of tackling it.
I found the threads and links on here showing the best way to do it and, being reasonably competent on the spanners, decided to replace them this weekend. I work about 8 miles from paddock land rover so on friday after work I called in and bought a front disc and pad set. Its all top quality gear and as cheap as chips.
I have changed loads of discs on cars before so allowing for the extra work involved in removing and splitting the hub I guessed that It would take 3 hours each side.
Yesterday morning (saturday) I jacked up the drivers side and took the wheel and hub off. So far, so good.
Next stage was remove the caliper so that the disc could come of and here is where it all started to go the way of the pear.
The caliper retaining bolts are a splined head and accept a standard splined socket from a normal socket set. The top one came out first, but it was so tight and stiff that I could only shift it with a bar on the socket, and with so little room to swing behind the caliper I could only shift it a quarter turn at a time so you can imagine how long it took to get out
The bottom bolt was a different story. I had been rounded off at some point in the past and the socket just wouldn't grip it.
I managed to get it out so far bu using a size smaller socket and knocking it on with a hammer but eventually that stopped working.
Out came the welding plant and with care and great difficulty I welded a M17 bolt to the splined head. It was really awkward to get the mig nozzle onto the bolt head and it took many attempts before I could get a good enough weld to let me turn the bolt out the rest of the way.
Once out, I modified the spline bolt to a hex head so that I could get it back in ( I know I could get new ones but it now saturday afternoon and I cant get one today and need the landy monday morning for work.
Disc off, hub swapped, disc and hub refitted. It's starting to go well again.
Until I moved the caliper back over the disc and the brake pipe broke.
The pipe fitting was well and truly seized in the caliper, so I had to take the caliper off ( again) and take it into the garage and grip the pipe fitting in the vice to undo it.
The other end of the brake pipe was still in the flexi-hose and was equally siezed. As was the other end of the flexi hose where it reconnected to rigid pipe.
Fortunately there was a connection fitting under the bonnet that wasn't seized so I undid that and took the entire assembly to the garage for a bit more vice work.
Finally, at 8.30 last night, the caliper was refitted and the flexi hose put back on.
Its now 8.15 Sunday morning, and I still have the brake hoses to get made as soon as the local motor factors opens at 10. Then I have to hope that the passenger side wont be such a nightmare and will be done by tonight.
Technically, its not a difficult job but if your thinking of tackling it just be aware that 17 years of corrosion and previous heavy handed owners may slow you down.

Well.

A good read I must say!

Points of note:

BE VERY WARY OF THOSE BI-HEX BOLTS.

A good bi-hex socket is a fairly rare thing as its not as easy to flank drive on a bibex but make sure you get one that fits good. Check your imperial set on a land rover always remember.

Plenty of lube helps, and of course they don't have to come out of the caliper, just enough to disengage the threads from the swivel hubs.

They are usually seized in though so it's never easy, drill the caliper to clean the hole and fit new bolts when you can.

Also, case in point, you have to remove the brake pipe bracket from the top of the swivel hub.

This means the swivel will leak some grease as the preload is removed but remove both bolts quick, move bracket and replace one bolt to minimise grease loss from underneath.

You can then move the caliper right out of the way.

SOMETHING WHICH MAY BE OF INTEREST TO YOU

Is that disco 1 rear brake hose replaces the front caliper solid pipe section rather nicely.

This means no more undoing swivel balls to move the caliper as its on a flexi pipe.

Best of luck today :)
 
8 miles from Paddocks? If you're near hucknall, I'll make you some pipe up if you bring me the broken bits.

I think that when they metricised the rangerover, they used a "near enough" approach and some bolts are still imperial head sizes and/or threads that just happen to be close to the metric equivalent... Certainly the brake caliper bolts suited a 1/2" much better than a 13mm...

Interesting info there guys, particularly replacing the front pipe with flexi.
I wasn't able to release the pipe brackets on the top of the swivel as I could only get a socket onto one of them, the brake pipe very neatly went straight over the other one leaving only room for a spanner and it was just too seized up to move with that.
I did however remove the retaining clip that held in the flexi which allowed enough movement to get the caliper off and out of the way without straining the brake pipe.
All in all, though, compared to yesterdays fiasco the passenger side today was relatively straight forward. The splined caliper bolts were in nice condition and came out easily and there were no fractured brake pipes. I did get a new brake pipe made up this morning at the same time as getting the two that needed replacing from yesterday and was going to change it as a matter of course but, although the union unscrewed from the caliper without any fuss, it was well and truly corroded into the flexi-hose. As it didn't look in too bad condition I decided to leave the pipe well enough alone.
Anyway, all done now. Finished at around 3 and had enough time to go and get some oil and treat it to a flush and oil change.
Bought a timing belt while I was at Paddocks, but might leave that one for a bit. . . . . . . .

Sweet, happy days :)

Few upgrades to consider for the future maybe?


Dont let my wife hear you mention UPGRADES!
I bought this landy (80k miles, f.s.h., 2 owners) purely as a tow vehicle for our twin axle caravan. It was just going to be a workhorse with no fancy bits.....
Unfortunately I'm getting carried away in the euphoria of landy ownership and now keep banging on about bigger tyres, suspension lifts, snorkels etc ( like when am I ever gonna wade???). I have already bought the steel tube ready to bend and weld into high cut off-road tubular bumpers. She's going nuts. Whats that famous Land Rover legend? One wife, leave it ?
Paul.
 
One wife, leave it indeed.

Well, lets not be so hasty, especially if she is fit as ####, but basically do what ever makes you happiest and live by your priorities.

Cheers!
