Alcon brake kits

[SMD]

E92 option Shane?

nice looking kit and great price. considering most people ditch the DS 2500s with the AP kit then makes even more sense.

lovely disc pattern and build and colour. would go well with an SB or SG CSL.

Thats interesting to know thanks, it maybe worth getting them re-bled when the car is back on the road in the Spring. It being DW, I would assume it was a proper job though, they're highly rated by everybody. They have GT1 etc.

Not judging their ability as I they seem to know their onions, but ive seen many garages bleed 6 pot calipers incorrectly, ie wrong nipple first.

If they used a machine to pressure bleed them then that doesn't work well I've found on the big brakes.

We do all the big brake kit bleeds manually.

Rick your brakes don't sound right after reading the roundabout scenario.

Found this as well. Usually do an initial bleed with the pressure bleeder, use Autologic to bleed the DSC & then finish off with a manual bleed. Almost always get some air out when doing it manually.

As has been highlighted, you should have little pedal travel with big brake kits, I'd definately look at getting them bled again.

Lawsy, Monkey thanks for the input. Given they cost a few quid and there's some uncertainty - it's got to be worth a second bleed to see if it makes a difference. They aren't particularly spongey but pedal travel is long.

Ha ha , Hope Yanto's not on line tonight lol.. Seems like a no brainer to me.. these brakes look the bollocks, Only decision for me is whether to bite the bullet and bust the credit card now, Or whether to do the first euro trip with upgraded pads/hoses/fluid and see 'how it goes' And potentially buy the F&R later in the year when funds allow and track days beckon. God my head hurts (And my wallet).

You need these. Once you start having it large on mountian passes or you get some turds pulling out on you in Belgium motorways you will want extra stopping power.

A BBK will give you the confidence to drive a lot quicker. Just get the fronts and forget about spending money on an intermediate upgrade of pads.

Just got the Alcon kit for my car awesome quality great bit of kit .:thumbs:

Got these Alcons too on my m3 track they look the tits but have't got to try them yet

Absolutely no doubt that the first thing to do on your CSL is to uprate the brakes. I run APs all round on mine and agree that they bite sharply and high up the pedal (or perhaps the bleeding was done very well). Also driven an E92 with an Alcon set up and it was equally good.

Pad choice is entirely another question. I made the mistake of fitting the wrong Pagid pads to my car and ended up smearing the discs. I run PF01 and they are awesome. RS29s are great too.

Hello all, this is my first post on this forum and I'm afraid it's a question. I don't have an M3 CSL but a Z4M Coupe - I hope that you won't all shun me as it shares some of the same components as the M3 CSL (although sadly not the engine upgrades or incredible induction noise):smt003.

I regularly track my ///M and find the stock brake setup ok but it lacks consistent pedal feel and can overheat (even with uprated fluid and EBC Bluestuff pads which purport to be for "race use only"). I'm planning to fit a supercharger this year and in preparation for this I'm undertaking a complete overhaul of the brakes and suspension. In February I'm fitting KW Clubsports with camber/castor plates, H&R ARBs front and rear, RTAB limiters, RE rear top mounts, OEM front strut tower reinforcing plates, and VT competition engine mounts. I'm looking for a BBK that will allow me to use all of this to its maximum potential and will handle what I hope will be over 500bhp.

Lawsy, I've been considering an Alcon BBK kit for a while having seen it advertised on eBay. The stock Z4M brakes are the same as those of the M3 CSL but I'm unsure if the BBK you're selling will fit the Z4M. Do you have any experience of this? My concerns relate to the size of the discs and calipers with respect to OEM style 224 18" wheels (I use these as my track wheels and 19" CSLs on the road) and also physically fitting the kit to the car (I think there may be issues with the dust shields when fitting all BBKs to the rear).

I'm not sure what the rules for Newbies are when it comes to sending and receiving PMs, but any advice that anyone can offer would be much appreciated. Cheers.

Welcome, nice post.

Glad you've never owned a Ford Cossie

[shane@mbtech]

The Z4m iirc uses the same brake set up as the Csl, so yes these should fit.

Regarding dust shields, most big brake kits require some dust shield modifying, par for the course. Very easy to do.

Regarding the z4 wheels fitting, I'm afraid I can't answer that.

Best bet with the rims is to take a front to a car with your choice of brakes on and try it. Otherwise all a bit of guesswork with so many variables,
