Title: Guide to Changing Calibra Brake Pads and Discs

This is a guide I have compiled to help everyone change their brake pads and discs safely.

Before taking your brakes apart, please make sure the pads and discs you have just bought are the same, as I have done this and it is not fun when you have thrown away the old ones to find the new ones don't fit >:( >:(

Also please make sure you have a 7mm allan bit or an 'L' shaped allan key, these are readily available from Halfords and the likes.

First up you will need the car jacked up with the road wheel removed, it also helps to stick the car into reverse gear for removing the small screw that holds the disc to the hub.

First up, it always helps to remove the lid from the brake fluid resevoir for pushing the pistons back
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0036.jpg)

Next step is to prise away (using a screwdriver and pliers) the spring clip at the front of the calliper
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0041.jpg)
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0042.jpg)
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0043.jpg)

Next prise off the dust caps shown by the arrows
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/Paintnumber34.jpg)
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0035.jpg)

Now you need to push the piston back into the calliper, otherwise the new pads will be too thick and will not fit back on, using a long flat bladed screwdriver, push it between the disc and the pad nearest the piston (the pad closest to the engine) If there is not enough room tap it in with a hammer. Remember this is ok as the pads and discs are being replaced.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0038.jpg)

Then when the screwdriver is inbetween the pad and the disc lever the screwdriver backwards and forwards until the pad is as far away from the disc as it will go.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0037.jpg)

Next up undo the upper and lower (Slider Bolts) using your 7mm allan bit or L shaped Tool.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0040.jpg)

And withdraw the calliper assembly remembering to tie it up and not leave it hanging by the brake hose as this could cause damage to it.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0044.jpg)

Now undo the two bolts/nuts that retain the brake calliper carrier (they are sometimeas different so I cannot specify what size they will be) and remove the carrier
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/Paintnumber45.jpg)
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0047.jpg)

You should now just be left looking at a brake disc, you will see a small screw, usually a phillips screwdriver fitment, undo this and withdraw the brake disc, the brake disc may be hard to come off, give it a few light taps with a hammer and watch your feet :D
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0052.jpg)

Now before fitment of the new disc, give the hub a good wire brush and a clean down with some brake cleaner, this will help the new disc mate flush to the hub and stop and brake distortion.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0049.jpg)

Also put some copper grease on there, it will make the disc nice and easy to get off next time
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0051.jpg)

Now with your new disc (I am using my old ones just as a guide) get the brake cleaner and a cloth and go over your new disc with it, the reason for this is most new discs come with a protective layer on them to stop them corroding in storage.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0050.jpg)

Now fit the disc to the hub, and replace the screw to hold it on
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0048.jpg)

And replace the brake calliper carrier
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0047.jpg)

And now for your new pads, first up discard the old ones, the one that is on the piston has little spring clips to hold it in, just pull the pad and it should unclip
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0053.jpg)

Give the edges of the calliper where the brake pads were a good wire brush aswell, again for a flush mating surface. Then put some copper grease on the back of your new brake pads
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0054.jpg)

The pad with the spring clip on it needs clipped into the piston, just push the two side clips in and push the pad in as shown in these photos. The arrows point out the two clip ends you need to push in
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/Paintnumber55.jpg)

And mount your other brake pad on the carrier where it would be if the piston was fitted, the picture shows an outline of where you should put the pad (the black and grey drawing represents the new pad)
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/Paintnumber58.jpg)

Now position the calliper back on the carrier until the two brake pads sit in their retaining slots and give the calliper a few soft thumps just to push it right onto the brake disc.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0032.jpg)

Now refit the calliper slider bolts with your 7mm allan key. It is recommended that you replace the bolts on your callipers and carriers but I must admit I have never had any problems fitting old ones again. This is of course your choice.
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0059.jpg)

Make sure that you tighten the calliper and carrier bolts to the torque setting given in the haynes manual. (although I find that doing them up nice and tight works fine)

Now remember to replace the cap on the brake fluid resevoir
(http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/DSCI0062.jpg)

Refit the roadwheel and lower the car, remembering to give the road wheel bolts a tighten when the car is on the ground.
Once both sides have been done, give the brake pedal a few pumps until it is resisting you pushing, this is when you know the pads are touching the disc and the calliper is against the pads.

Last thing to remember is the brakes will need bedding in, so no heavy braking for the first hundred miles or so, otherwise you will ruin all your hard work and effort by warping the discs. Enjoy and any questions PM me

If you are using new discs and pads there is no need for bedding in.

You would need to bed them in as braking would be underwhelming until the pad has shaped to the disc, from what ive learnt anyway

That's required with new pads and old discs, that's what i was once told.
Title: Re: Guide to Changing Calibra Brake Pads and Discs
Post by: Phil. on March 31, 2007, 20:52:03 PM
Youd have to let them bed in, you could never guarentee that the pad will fit on the disc straight from fitting
Title: Re: Guide to Changing Calibra Brake Pads and Discs
Post by: Ben on March 31, 2007, 21:06:16 PM
surly all new pads with new discs have to "bed in" as all the area of the new pads will not necessarily touch the disc (until all the high points have worn down on the pads)

more to the point --- an absolute top class guide!!! been waiting for this help as mine need doing  :)

Thanks very much
Karma awarded

After fitting new brake pads and or discs IT IS advisable for a about week to only limo brake.. New Pads and discs do need settle and bed in. Its better to be safe than watch your motor head off into the sunset on the back of a tow truck...

Absolutely fantastic guide ! The only slight criticism I'd make is that you didn't say to replace the dust caps and spring clip but other than that, really awesome guide

The pics are at http://s139.photobucket.com/albums/q291/Calibra_se8/Project%20Cally/changing%20brakes/ if anyone wants them ( I searched photobucket for 'em, dunno if any of the mods can fix this so the guide points to the pics )

how long should it take to do this???

im not really mechanically minded as such but quite happy to give it a go - it looks fairly simple to do myself - is it worth attempting or easier to just get a garage to do it?

Its definetly worth tackling yourself mate! leave yourself a goods few hours to change them and follow the guide and all will be ok.

Tools required are pretty simple really, a socket set, wheel brace, basic car jack, allan key bits to remove your caliper and carrier, some copper grease, brake cleaner and a Philips and Flat screwdriver and a set of pliers :)

I used this guide ( in fact it was me who refound the pics when the link was broken LOL ) If I can do this job then anyone can, it's really quite simple. The only thing I'd say is that you'll need a bit of strength to undo some of the bolts as mine appeared have threadlock on them. Nothing that a bit of elbow grease won't cure !

Yes agreed, its tough on the old muscles but once you are there its a great feeling, as long as everything is nice and tight on refitting ;D

great guide mate ;)

i personally use slip joint adjustable pliers to compress the piston in the caliper tho. when doing your back discs and brakes you need to have 2 new "anti-rattle" clips for the rear calipers and you may also need to loosen to handbrake adjuster to slacken the contact between the handbrake pads and the inner disc surface ;)
Title: Re: Guide to Changing Calibra Brake Pads and Discs
Post by: Gobbles on December 02, 2009, 13:20:05 PM
Where can I get these anti rattle clips from? Or will they come with new rear discs and pads?
