Brake pads and fluid?

[Will]

I'm with Rich on liking DS2500s for road use, fine even from cold, they're pretty decent all round really, had 3 sets in my time....you do need to bed them in good and proper though, if you don't they are pretty wooden.

You must learn to appreciate brown wheels if you get them though, as they are very dusty!

Turns out I need new pads sooner than I thought. I can't be doing with spending a lot on them so it's between Yellowstuff or Mintex M1155. Opinions?

What would Keiichi Tsuchiya use?

looks like i'll go for DS2500, found them for £123 in the right fitment. Shopping list:

Brembo vented discs (£83 total)
DS2500 pads (£123 total)
refurbished e46 330i Calipers (£96 total)
RBF600....how much of this will i require? it seems to come in 500ml bottles...

Should i bother spending the extra £70 on braided hoses whilst i'm doing all this?

Also, i need just the carriers to go with with calipers, most breakers only sell used carriers WITH the calipers yet re-manufactured parts only come WITHOUT....damnit.

i need two bottles for mine but best to ask on model specific forums or check your handbook.

i would go for braided hoses tbh. its not going to have a negative effect and its less than the cost of a tank of fuel

it's more hassle though as id have to start mucking around with the rears too which are otherwise being left for the time being. also, a tank is £60 on my car

whilst gibbo has pretty much the most experience of anyone i know with the subject matter, the DS2500 having that feeling comes from them being poorly bedded in or not recently going through the bedding in procedure.....

....running Hel lines, RBF600 and DS2500 on OEM honda discs. its a brilliant setup for my car. tbh, i would take a look on the model specific forums to see if there is a 'go to' established set up.

As I stated earlier, I'm running the same set up of lines, fluid & pads as Rich...My DS2500's don't feel wooden at all. I've got as much, if not more, feeling now than I had before and they are very progressive.

Be aware that I also got the hard lines changed on the rear of my car when I changed the brake lines because, typical BMW, they had corroded, but that only cost an extra £15. Couldn't really tell you if the lines improved anything or not because of the other changes.

RBF600....how much of this will i require? it seems to come in 500ml bottles...

I bought three bottles of RBF600 for mine and there are more than a few similarities between your Z4 and my 130i. I believe that the loop is a little over 1.1 Litre to fill completely and it's best to have a bit extra for bleeding.

Just get them fitted. Don't be such a pansy!

I thought you'd prefer using your foot on rock hard things

DS2500's are a great choice for road use imho

 

[Gixer]

Another vote for DS2500's here. I had them on my car in combo with Brembo disks. As everyone has said run them in like they say and they'll be great brakes. I am lucky where I live as a section of the M271 is between two roundabouts. It's just right for getting up to speed and braking for the roundabout, progressively harder and harder.

I couldn't fault them on the road or track in my Gti6.

Put simply, don't waste your money on RBF600, get ATE Super Racing Blue. There won't be any difference, you won't boil either

ATE - 1000ml = ~£13
RBF600 - 500ml = ~£13

Put the money saved towards some braided hoses to firm up the feel nicely.

Simples

Yeah all performance pads need that re-bedding after prolonged mild use, not the worst chore in the world

Ohhh reallllyyy

No Bedding In
Due to the CL Brakes race brake pad unique sintered metal compounds, no material is transferred to the disc when used. No bedding in procedure is therefore required.

balls! my needed it after Llandow then a week of commuting, came back to me then

 

[-Ad-]

I just drive it normally then sometimes if it's been sitting a number of days/week take it around the industrial estate by work for a few harsh stops to get the rust off the disks and them working in harmony.

No bedding in needed as they just spew their and disc dust all over the wheels

I hadn't noticed

 

[rG-tom]

Muffin, didn't you boil ATE superblue at Llandow?

 

[Clarkey]

Super blue racing has a boiling point as high as any other, boil that and you will have the same problem no matter what really.

 

[Berger]

Bigger discs will slow you down.

Increasing rotating mass away from the hub

I preferred DS2500 over M1144.

I didn't, Lewis Hamilton Jnr did...but yes and it was super fresh. Brakefluid absorbs water over time and that causes the boiling point to lower (Wet fluid).

Super Blue is fine for the road but on the track it showed up, I'm going Castrol SRF next time and some ducting

Super Blue:

Dry: 280
Wet: 198

Castrol:

Dry: 304
Wet: 270
