Front Disc change

[glanrichbex]

Hi all,

After crawling under my truck ( as you generally do on a Saturday afternoon ), I noticed only 1" in the centre of the back of the discs is shiny, the rest is rust. This may explain why my back wheels like to lock up as my front breaks are obviously not as efficient as they should be.

I took a front wheel off a while ago and it looks like changing the disc is not an easy task. Further more after looking on fleece bay I am confused as to which disc fits.

The set up I have is 6 wheel bolts with an inner 6 smaller bolts, there is a black shiny metal dome in the centre. Its a 2005 2.7TDI Terrano, any help would be greatly appreciated.

Cheers

Rich

Check the downloads section.

The downloads section should show you how to do the job.

If memory serves me right there is workshop how to in the downloads section, one of the first jobs I did on my Mav, fairly straight forward unless you have siezed or broken parts.

Downloads section

If you look at the section for front wheel bearings this covers the disc removal.

Sounds like the sliders on the front calipers are seized, two each side.

Also the small dome in the centre with nuts onto studs is your fixed hubs. The downloads section may well show auto locking hubs but no real biggy.

Sorry to be a pain - I can't see where the link to the downloads section is

OK first things first, only go to your local motor factors for disks, about £20 each if I recall, reason being there are very many shady imports that a recent TV documentary discovered that they often break up under strain, so not worth the risk in order to save a couple of £s.

No the job, apart from the obvious like jack up and support, and remove wheel, next remove small black cap on hub (tap with chisel and hammer it is just a push fit, then remove circlip, now remove the nuts and the fixed hub, store in a clean box, now remove the two 13 mm spanner size bolts that go into the slider pins on the caliper and lever the caliper off and support out of the way with no strain on the brake hose, remove the brake pads and store, now with a long bar remove the two 19mm bolts holding the brake cradle on, then remove the two small x head screws on the hub bearing lock nut and remove the ring, next unscrew the bearing adjusting nut and remove the bearing and pull the hub and disk off, pack the bearing holes with clean paper or rag and undo the bolts holding the disk to the hub, you may be lucky and a few taps and it will come off but you may not and it may need a lot of thumping, have a light clean up on the mating surfaces of the hub with a bit of fine emery paper, offer the new disk up getting the bolt holes nicely lined up (I use a couple of longer bolts to do this initial line up as once you have pushed it on enough to get the original bolts into the threads if you are a tiny but out they will not catch and you will have to knock it off again) then refit the bolts and tighten them up opposite sides equally to draw the disk on, when seated tighten them up, I have a torque wrench built into my arms, but being brakes you may want to use a proper jobbie, the rest is a reverse of the stripdown, apply some new grease too the hub bearings and of course degrease the disk, and tighten the hub bearing hand tight plus a bit less than a quarter turn, job done you can do the other side easy now, Rick

I know I could of said go to the downloads, but have had a hard day and found it therapeutic to engage my mind and write it down, one thing old Rustic picked that I forgot was check the pistons and indeed slider pins, Rick

 

[jims-terrano]

Would you recommend new pads at the same time? That's the way that I have always done it as old pads will have worn into any grooves or ridges from old disks surely.

 

[solarman216]

No question new pads an absolute must, sorry not to have mentioned that, I just assume that when people buy new disks that pads are automatic, bit like oil and filter, Rick

Yup +1

Success .....almost

Many thanks to Rick for the excellent description, I did the deed earlier this evening and I don't know what I was afraid of. I went to our local motor factors and bought discs and pads ( came to £95 inc vat ..... may have paid a bit much there :doh ).

On the way home from the motor factors the ABS light came on

Thinking this was a straight forward broken cable, I half expected that I would be able to get the soldering iron out and do a repair. I proceeded to remove the offside front wheel and was greeted with a horrific sight....... the abs sensor lead was wrapped around the drive shaft and snapped out of the sensor!!!. I can work out what has happened when I started on the near side brakes. The bracket supporting the abs cable was cable tied onto the upper arm and I then saw the bolt that should hold it had been sheered off some time in the past. I suppose the cable tie on the off side had given up the ghost and the metal bracket had fallen down and caught in the CV boot and wrapped round. Luckily the CV boot is not torn and all I have to do is buy a new sensor. That was a bit of a job getting the remains of the old sensor out - absolutely ceased solid!!

I have brakes!!!! :clap:clap

but I also have an ABS light on :doh

Glad you've sorted the discs and pads.
Those jobs just keep coming don't they? :thumb2

 

[terranosaurusdoug]

It might be worth taking the abs fuse out as rick suggested in another thread earlier, that way you won't get it kicking in and causing you stopping problems, read this thread :thumb2

ABS wrap round problem

I feel your pain you did well to get the old sensor out they can be a pig.

 

[glanrichbex]

It was a real pain getting that out but had to because it's nacked

I went to our trusty motor factors today to enquire as to the price of a new off side front sensor. When the guy said 192+ vodka and tonic I went into tunnel vision and my wallet made a grab for my leg.

I see they are on ebay for about 45squid - anyone had any experience or know where's the best place to lay ones hands on such an item?

Cheers
