thanks to thetomc i shall soon have some 323i calipers for the front!! i've ordered some ferodo DS2500 pads but just OEM discs but surely this will be better than solid grooved rotors!? i'm guessing stopping power is not improved, just cooling?

in wales it's proven quite easy to cook 316 brakes due to the large gradients. should i be looking at uprated fluid too, or will the pads and discs be suffice? if so, recommend me some fluid

thanks guys

Are you fitting vented 323 discs too?

yes, but they are not grooved or cross drilled, but are the 22mm wide vented discs. 323i front brakes offer no extra stopping power, is that correct? or are the pads larger? i know the disc diameter (255mm) is the same.

cheers mark.

Cooling is obviously better though. You could always try alternative pads? I've been using EBC greenstuff and have just bought them for my Volvo upgrade too. I know not everyone likes them though. Dot4 fluid is a cheap enough upgrade and braided hoses.

i've gone for ferodo DS2500 pads. i've got green stuff's on mine yet still cook them (well, i think the discs or fluid overheats before the pads....)

regards fluid, what's the deal with the dotx.x, could the E21 take dot 5 or whatever or does it have to be a certain grade? if so, how about this?

Dot5 is fine I think, although I might have read you shouldn't mix with other types?

Brakes fade due to excessive heat so once you deal with that you should be fine. Braided hoses will give a better pedal too imo.

was just about to order some from demon tweeks but they can f*ck off if they want £8 for posting a small bottle. where else can i get uprated brake fluid?

thanks guys

f*** should have them!! well can check!

can anyone just confirm how much i'll need?

cheers!!

probably but a liter or something BUT WONT take all that !! i would flush thru with new brake fluid its why i would get a liter, maybe little more depending how much you may lose when pumping as it gets messy, but fitting only calipers and topping up then you buy the smallest tub available... Renew your fluid!!!

fluid is about 18 months old, how often is it meant to be changed? i might not get the fluid done next weekend when i go to tomC's, but wait another few months and get it changed and get some braided hoses. or will i need some brake fluid when i change calipers (i.e. will there be any fluid loss when changing?)

mercedes recomend change fluid every 4 years, brake fluid does have a shelf life. and if you are getting it posted to you allow the fluid to sit for a day in the bottle first to let the air rise out, and dont shake it before you put it in, every little helps

how about aldo cutting the rear shield of the brake disk so more air gets in that way?

in that case i'll wait, but will it lose any fluid when changing calipers?

thanks mate

yes a small amount, you will need to bleed your system once completed
and you need to pressure bleed it aswell so grab a mate

I wana know how you get on! just done the same to mine and ive got spongy brakes although there may be another problem.

They are a simple straight swap aren't they?
