Hi All,

I have just had the wife’s 07 3.0is "COUPE" serviced, BMW has suggested it requires new front and rear disks and pads (there are currently no warning lights?) and a replacement of the brake fluid.

I have a quote for Pagid OE quality items all round for £230, are there any other alternatives you guys can suggest?
also what would be the best brake fluid to go for? are there any improvements to be had?

cheers rob,
 
Euro Car Parts, I think I paid about 70 quid for a pair.... pagid/textar OEM stuff (made by same company) . After doing it a couple of times it really is a DIY job if you can take the wheels off

1. Jack Car Up
2. Take Wheel off
3. Undo the 2 large bolts on the on the back of the Caliper
4. Undo the hex bolt that holds the disc on (allen key set needed)
5. Tap the disc with a hammer to loosen it
6. pull off the disc / slide on the new disc
7. Take the cap off the brake fluid tank.
8. Place something like a piece of wood (that won't damage the pads) inbetween the brake pads and lever them open a little to make it easier to slide back onto the disc.
9. Slide the caliper onto the disc
10. Grease up the bolts and put everything back.

I also like to paint the inner part of the disc with hammerite so it doesnt rust.

Takes me about 30 minutes now per wheel if that....

As for brake fluid i think everyone recommends standard stuff unless tracking...

btw The rears are a little harder as they have handbrake shoes inside so more tapping with the hammer required. :D

almost sat waiting for my brake pad warning light to come on so i can upgrade to these http://www.mtecbrakes.co.uk/index.php?main_page=product_info&cPath=7_12_83_93&products_id=15072
which at 50 miles a week could be a while :)
 
Buy the parts and fit your self as mentioned above if your willing. I paid about £78 for the rears on mine and fitted them one morning while I was off work. It was my first time, found plenty of guides online for reference.
 
I really thought the brakes on this would be über complicated but this and other posts make them look as simple as the ford ones. I strongly recomend doing them
Yourself as its well satisfying when your done and if your careful and take note of how you took them appart pretty easy
 
I'm about do replace mine on my 03 2.5 sport doing the 300mm upgrade from here: http://z4-forum.com/forum/viewtopic.php?f=24&t=8399

A question I have is looking at this post: http://m3.madrussian.net/diy_front_brake_pads.shtml
They state using a anit-sqeel compound, is this necessary?

I thought the oem pads had an anti squeal backing but I would still put it on anyway

Squeaky pads are annoying and sound rubbish

You can use copperslip instead if you have any in your garage, that's what I use

Sweet thanks for that! I have one more question now before I'm finished with them. I just did the passenger side and had to take a break to shovel snow.

My brake pad warning light came on 3 separate times before, which was what caused me to want to do the upgrade. it came on intermittently for 15 seconds or so 3 times on different days driving a total of about 20 miles. The car has been in the garage ever since. I already have the new sensor to replace, but now I was wondering is it necessary to replace it since the light was not on continuously?

I replace mine even if they light hasnt came on

For the minimal cost involved is it worth it? Taking them all apart in a week when the lights on

Yup it needed it :wink: once I got everything apart saw it was worn so I was like what the hey LOL so all done now. Thanks. Now I'm going to have a new thread for a whole bunch of other issues I found when changing out the brakes.
 
I got mine from GSF car parts.

I got Brembo rear discs & pads for less then £100. Getting a mate to fit as i'm too scared to do them myself, although i know i should as it's easy!! What's the best guide to follow if i did?

It's really not bad at all to do, though I know the paranoia feeling. I was using this for a reference and how to guide: http://m3.madrussian.net/diy.shtml
 
Ok, an update for anyone after rear discs for the UK 2.5si

I've had a bit of a game, but finally managed to get hold of the right Brembo discs. (Vented). It appears that the 2.5si shares its brakes with the 3.0i

If you use GSF, it lists several, but some that come up DO NOT FIT!!

The correct part is GSF part number 603BM0380.

This is the Brembo OEM part - number 09.9869.80

Hope this helps someone in future! (i've had 3 sets lol)

nice list :thumbsup:

only thing i would say do different is not to push the fluid back into the reservoir. instead leave the cap on the bottle and open the bleed nipple when pushing the caliper piston back in. i do this for two reasons. 1 i found it easier to push the piston in when im not trying to back up the brake fluid system on several cars (this may just be me) and 2 your not forcing fluid back through all of the valves in the system on the reservoir etc which if they are a diaphram may cause an issue.

obvously this is irrelevent if your going to replace the fluid and drain the system.
