My understanding is that the pagid disks are the oem disks - just without the bmw stamp.

Running a pair of pagids on the front of mine with no problems. Identical in every way to the OEM as far as I could see when fitting them.
That's interesting. I've been trying to track down the BMW OE manufacturers for my M5 brakes to try and save some money but got nowhere identifying who makes the brake disks.

Had a bit more luck with pad manufacturers. The rear pads are definitely Textar (since a dealer fitted the last pair to my car + they have Textar embossed on them) and I think the front pads are Jurid, these:-





Not 100% convinced yet since they seem to be specced for quite a few other models. Anyway, I will give the Jurids a go. It's wearing Ferodo Racing DS2500 pads on the front at the moment, but with only another 10k miles of life in them, probably. Be interesting to see how the Jurids shape up.

For those interested, the Jurid pads are available for £48 delivered on eBay, and includes a brake sensor (C3BMW ebay shop):

Might be cheaper sourcing direct from C3BMW. Best BMW OE price I could find is circa £130.

I was looking at these - price has dropped slightly: http://www.ebay.co.uk/itm/BMW-Genuine-Front-Brake-... I will admit I didn't shop around much.

The Pagid ones were just shy of £200 each fitted by M-Tek Northampton. There are all sorts of things I could have done differently but the reality was I needed the car back and I couldn't face putting the discs that were juddering back on. The OEM discs were fitted by the previous owner just before I got it. I still have them - planning on having them re-faced.

OP (to drag it back on topic): a lot of sound advice above. The issue you will have is finding a car that doesn't need something being spent on it, whether it be rust, suspension, or general wear and tear. I spend a good 9 months looking until I was most fortunate to stumble across 'my' car. It has a mountain of paper work (I need another folder), and you'll want a car with an equal amount of invoices, otherwise you'll need to assume nothing has been done, and be prepared to throw an awful lot of money at it depending on what you want to achieve. Don't be put off though, get behind the wheel and you very quickly forgive the car any number of sins, it's joyous. A small thing but check the battery - there are too many cars about with under-sized batteries, the engine needs a strong, healthy battery to turn over cleanly. It should fill the whole tray in the boot and rated well above 90Ah.

Can't recommend Phil at CPC enough, he really knows his stuff. It's a shame it's so far away (Amersham) but for anything not routine it would be my first port of call everytime.
You can buy pair discs for £390 from BMW dealer in Plymouth.

Front discs are only made by one company - ATE so buy them from wherever you can get them cheapest - Pagid, ATE, BMW, Zimmermann

I used brembo pads on the front of the vehicle - P06021 is the part number.

I bought APEC rear discs DSK2739 - £30 odd each, and brembo pads again - P 06 020

I figured most of the braking is done by the front so saving £240 on the rears to see how they work is worth it, plus APEC aren't exactly unknowns either.

Brake discs for example are BMW only if you want the brakes to actually work.
I disagree. In fact I'd avoid the OEM discs. They cost a fortunate (£542 for each front disc last I checked) for a start. Despite very gentle use, my front discs started giving a horrible judder every time I went near the middle pedal. Eventually caved and had Pagid discs fitted (and new fluid at the same time). So far, much better - but perhaps too early too tell. The brakes aren't spectacular compared to modern cars, they need working and can initially seem soft, but they will stop the car. The upside is they are nicely progressive and allow you to be smooth on and off.
Well maybe I should expand, I spent a lot of time looking at all the forums about brakes and brake upgrades (some of which really aren't) for the M5 after realising the discs and pads all round were screwed after a visit to the 'ring and Spa.

The OEM discs from BMW are the only ones that are two piece discs from what I found, if anyone has actually bought some that are floating discs that weren't direct from BMW then I'd love to know where you got them. That is why all the cheap discs which claim to be for the M5 are in fact a waste of money as they're all single piece discs and aren't going to cope with heat in the same way. The best I found after reading a lot was to keep OEM discs, upgrade the pads, fluid and fit stainless brake lines. I got all news discs and bolts from BMW Plymouth for around £550, Pagid RS29 Pads all round (as they were one of the few that does front and rear in the same compound) for £460, Motul RBF 600 & Goodridge stainless hoses and the brakes have been excellent ever since I have also not managed to get them to fade once. The one annoyance is the pads squeal like a bd but I've almost got used to that.

European spec M5s got 2 piece floating disks, US spec M5s got single piece disks, all the after market disks I've seen are the US type one piece.

Pagid, Zimmermann, ATE, BMW all supply the same 2 piece discs, and probbably more.

Are the BMW numbers.

Cheapest place I've found is
http://profiteile.de/catalogsearch/result/?q=34112...

at just under £300 for the pair.

Those pads are hideously expensive, you can get brembo ones cheaply or the ATE "ceramic" whatever that may be here

Thanks for the advice folks. Picked up a Dec' 00 LeMans Blue M5 (01 MY) on Christmas Eve for a bit of a steal. 119k, heritage leather. Picked it up knowing it needs a new thermostat and a good look at the brake judder, but for the money I paid it'll all come well under budget! Merry Christmas.

How much did you give for it?

Chasing brake judder might not be as cheap as you hope it is! I'm chasing it at the moment

We have had more positive feedback from Lumag pads than Pagid and Textar

If you can get them I definately recommend them.

Its the disc's, bushes and how the planets are aligned that can affect brake judder on E39's rofl

Merry Christmas indeed, if the weather improves I might take mine out for a blast at the weekend. Enjoy it, they really are a cracking bit of kit.

I'm going to drop it down to my mechanic soon, leave it with him for a week and some money to sort it out.

Today though I'm going to steal bits off the 540i to make the M5 better, got 2 dead parking sensors on the M5 and a broken button on the aircon unit.

If I said what I paid began with a 6 would you hate me?

Hopefully he will sort it for you cheaply! I know of someone who had it and it was down to how his wheels were fitted!
Poor 540i! lol

Not at all, I paid with a number than began with a 5 last year, but tbh I should've waited longer and paid more, but you know how it is!

We need pics man!

I chased brake judder on my E39 M5, even with new disks , pads and bushes it continued. Eventually I had the disks skimmed on the car and on the recommendation of the chap who did the skimming I had the rear face of the wheels where they bolt to the disk machined as there was a paint build up from the refurb. The skim and flattening of the mating surface of the wheel completely eradicated the problem and the brakes were as smooth as butter for the next 5000 miles till I sold the car.

Sorted my judder with new OEM front pads and discs. Not cheap!

Bought the car in early Summer and it had judder from day one if braking from high speed, so I bit the bullet and replaced the pads and discs. I read somewhere the M5 setup is susceptible to material transfer from the pads if they remain in contact with the discs when hot (eg waiting at a red light with brakes on after braking from high speed).

I had Pagid discs and whatever pads are OE (I cant remember the name, but the discs and pads are the same as BMW ones but without the stamp and the disc's are the two piece ones) and the judder remained. I've replaced the brake reaction bushes and the judder remained.

I've had it before and it was the rear brakes that were causing it on an MG ZT I had, so I am going to replace the rear brakes. They could probably do with replacing anyway.

The car has only done 30 miles in the last year so I'm expecting a few issues, did well though considering he wanted £9k!

Will get a thread up in Reader's rides and post a link here.

Mike,

Re. the judder you're chasing down. Consider checking your wheel bearings. I had this on my M5 and finally sorted it after all the 'usual suspect' suspension and braking components had been gone through one by one.

The wheel bearing wasn't making any noise at at all when driving it, and seemed fined just spinning the wheel to check for roughness when it was on a 2 post lift. No sign of movement either when doing the push/pull at 9 o'clock/3 o'clock & 12/6 o'clock test. But holding the coil spring when spinning the wheel revealed the fairly minor vibration - short generic demo vid here:

https://www.youtube.com/watch?v=bzB-V8CrSn8

Wheel bearing changed and the judder disappeared (it was a front wheel bearing).

An easy & quick test. Might be worth a go?

I am told M5's dont like to be laid up for long, but I think that can be true of most cars. I don't think you should find too many issues.

What are the jacking points like?

When you replace the thermostat, replace the two hoses below it if they've never been changed - they're cheap and so easy to replace with the housing removed.

Forgot to say - Pleased you have bought one smile

I'll give that a go - I'm going to my parents tomorrow and they have a jack so I'll jack it up and get someone to spin the wheel!

Cheers!

ETA - scratch that, I can spin it myself hehe
