M5 (E39) Brakes

Recommended Posts

Mine have decided to start shaking.  I knew I was going to have to replace them at some point, but looks like its now.

 

The standard brakes aren't all that cop and bloody expensive for what they do provide (something to do with being 2 parts/split????).

 

I want an alternative thats better performance but not going to destroy my wallet.

 

What are my options?  Front and rear.

Standard M5 discs, you'll have the floating rota two piece design. These are lighter and disburse heat more efficiently than solid discs. Solid discs are cheaper, so often get fitted by people cutting corners and don't have the same heat dissipation features which could lead to warping.

I've got a quote in the last month from BMW £477 for the correct floating discs and something like £225 for the pads. So those BMW performance ones don't seem to badly priced!

As above, but most likely is your shuddering is actually down to worn thrust arm bushes, not the discs.

 

easiest solution there is to powerflex the arms. Personally i'd be going down that route first as opposed to new discs which are expensive.

 

You can source the OE 2 piece discs from ECP which work out a bit cheaper using their discount codes, still a lot more than new bushings for the arms though.

 

If you look at my threads there's a DIY on powerflexing your arms

Called ECP and they've done me a really good deal on Pagid disks and pads for around £340 all in.

 

Thanks for the advice guys :)

I'm now intrigued by the brakes listed at the top (performance brakes), are they really only £1k all in (except pads) for all 4?

Well guessing you've found out. You only get the fronts, which isn't bad considering from BMW you could be spending £750 on originals.

No idea how much the extra brackets are needed to mount them.

Answered my own question discount code will reduce the price down to £314 HOT30

I called my local branch.  They applied a discount as a forum member which took the price of each disk down to £156.

I got mines for £127 each from the glasgow branch.

I think I need to remind my local one about my trade account, that's pretty manageable really

Highly recommend you fit stainless brake lines if you're changing disks, had mine fitted today and the difference is unbelievable! Pedal feels nice and firm and really inspires confidence in the standard brakes! Well worth the £70!
