Some braking advise

[ade36]

Looking at improving the braking on my 318 from 'hang on and hope you coast to a hault before you hit the object in front' to actually working.

It's a 318i Lux so there's drums on the rear.

My plan was to convert the rears to discs and run standard discs and pads there, then uprate the front with aftermarket discs and pads and bleed the lot with new fluids.

Is it worth swapping the fronts with those off a 325 or have most models got the same disc/caliper combo up front?

[redcar]

Front 325i discs are vented so are different, as are the calipers

[ade36]

Do they use the same carriers and are they the same diameter?

[Motorhole]

Carriers are different too but discs are same diameter. The calipers for vented discs are wider, vented discs won't fit in the gap between the carrier and caliper for solid discs.

I think I have a decent set of calipers somwhere.....

[ade36]

Other than the cooling benefits of the vented discs is there much to be gained? Is it worth swapping I guess is my question?

[redcar]

Of course
Vented makes a massive difference mate

It's easy to swap the fronts
Get braided line while Ur at it, and try to look for refurbished callipers

So all you will need are the calipers, disks and pads or will you need to change the front end

[Motorhole]

Yep, all you need are calipers, discs and pads!

...and carriers

[redcar]

front:
calipers, carriers, discs and pads

rear:
brand new handbrake cable for disc brake rears
whole trailing arms with everything on them

[Motorhole]

Be advised changing trailing arms and handbrake cables isn't a pleasant job

[mrb27]

id do the trailing arm bushes too while i was there..

[ade36]

Yeah, bushes would be a no brainer once the arms were off. Just need to keep an ear to the ground for some rear arms... At the right price!

so you can do run 325 breaks on a 316/318? even tho there on the smaller struts?

fluid, pads & discs - maybe a cautionary overhaul of the servo etc..
