Front disc removal

I have just bought a set of discs and pads, the pads are wrong but that's life, what I need to know is how do you remove the disc, do you heed to remove the large nut in the centre of the disc or should it just come off when you remove the two locating pins.

advice would be appreciated, cheers.

Hi.

Large nut.. ?

In the centre of the cars front HUB there is a HUGE NUT.. that holds the driveshaft.


Traditionally.. the hub will have 2 x small SPIKES for locating roadwheel.

You undo these.. to de.mount the brake disc.

To swap discs you will need to remove the 'frame' that carries the brake pads.

Re: Front disc removal

Iím going to be that guy. If youíve not done brakes before as seems to be the case, either pay someone to do it for you or have someone experienced to talk you through it. Itís an easy job, but itís also easily screwed up and with serious consequences.

Op.s

Previous thread was about buying the parts..

And they posted links to videos.

You would have thought that a 'how to '
video may have have been informative enough to get the Correct parts .
and show enough detail to cover what needs to be removed though...

Re: Front disc removal

The video is fine but my brakes are different to that type, also changing the discs and pads is Ok I am happy to do it but just never done this type before, the next problem I have come across is the two bolts that hold the caliper to the frame on are not hex head bolts but some kind of spline type, does anyone know the size of this, I know its not 14mm as I have one of those and if you know the size what is the correct name for the socket I need to ask for.
I have put it all back together now as the pads and discs are not that bad but this has been a valuable look-see

Cheers

Re: Front disc removal

I now see there are two brake systems one Bosch and one Bendix, how do I tell, the pictures of all the pads I am looking at are different to the type I have fitted, they seem larger than the ones I have bought and also have hooks at each end to achieve the fitting.

You didnt see the branding on your caliper?

What kit did you buy?

Re: Front disc removal

I bought a Brembo kit after putting in the details of the car, so I thought I was getting the correct kit, I now know the tool I need is a female torx socket which is ordered and there is a Europarts store near to me I will go in and actually se the pads before I pay for them.

Good idea.

When ECP and other factors deliver brake parts to the trade, they will often send multiple sets, with instructions to return the ones that don't fit. If you're buying them yourself, you can always order both types and return the ones you don't use - the factors understand the difficulties and are usually helpful and cooperative. Fortunately aftermarket brake parts for the 500 are cheap.

Beats having the car up on blocks and finding the only parts you have to hand won't fit.

You might find this thread helpful - the principles hold good for just about any car you might have to work on.

Make sure the car is securely supported and that you have a good quality allen key socket before attempting to undo the caliper mounting bolt; it can sometimes require considerable torque to loosen it. All the rest is completely straightforward on the 500.

Re: Front disc removal

I have been dumb, never thought to actually check the disc size, I just punched in the information and took the kit they sent, turns out have 257mm disc fitted so I just need to see if I can return them and get the correct fitment and I will be fine.
otherwise there will be a complete setoff Brembo discs and pads for sale for a good price on here shortly.

I find myself agreeing with 306maxi, please dont mess with brakes if you are unsure. Get a tame garage or a competent friend to sort it for you.

Tony its worth downloading the eLearn CD image from this site as it has the procedure for caliper and disc removal documented.
Ideally you could also do with a torque wrench, some thread lock for the caliper bolts, a bungee to support the caliper and some brake cleaner (excellent for cleaning other greasy jobs).
Try to get a fitting kit with new pins and clips. Some pads come with them.
The disc is only held in with two locating screws do son't go undoing the centre bolt..
Remember when you wind the pistons back in the caliper (a G-clamp and small block of wood is handy) to check the brake fluid level.

What centre bolt??

Often better to bleed off excess fluid.. rather than risking 'backflushing crud'

Re: Front disc removal

What centre bolt??..... Hub Nut!!!!!!

Always best to clamp Flexi-hose and push back caliper piston pushing some fluid out of a slightly cracked bleed nipple. This will remove a small amount of fluid from the system and the master may need topping up after bedding in new pads, but this is a good option as the fluid that has been removed has been exposed to the most harshest conditions and may have deteriorated slightly.
