Brake upgrade

Post by CharlieEdwin » Sun Jul 08, 2018 10:38 pm

I'm thinking about upgrading the brakes on my e87 120d. Are the brakes from the 135i worth it? Or shall I just put in a EBC brake disc and pad upgrade kit?
Or any other brake upgrades people recommend?

335i brakes have my vote straight easy swap. A good upgrade for non 135i cars. And discs and pads are cheap

You could get a set of M Performance (blue) or the BMW Performance (golden yellow) brakes for the fronts. The blue 4 potters are meant to be better...

Cool, so what’s needed for that 335 brake upgrade? Discs, pads, callipers and carriers? Anything else?

Also, do both 335i and 335d brakes fit and how much bigger / better are they than a standard 123d?

Cheers for the assistance, this looks like a great mod.

With the 335i calipers they run a 348mm disc. I assume this will fit fine with my 18" wheels? And as previous asked what's need to secure these?

These are 335i calipers with 335i rotors (348mm) with 18” wheels. They just fit

Slightly off topic but relating to brakes... Does the E82 135i have the kevlar reinforced brake hoses like on the F series X35/X40's?

If they don't then braided hoses could be a good addition to your upgrade plan.

I had Goodrich steel braided lines in my civic and the pedal was hard. I do prefer not having them as it’s nicer for a daily in my opinion but each to their own

Hi guys,

Pretty interested in this upgrade for my e82 125i

Can someone answer the following ?

Is this a straight swap eg original lines used ?

Do these fit under 18” 261 without spacers ?

Thanks

I used the brake hoses that were on the car which were e87 120i. You just need 335i front calipers and brackets. I have not installed the 335i rear brakes

Perfect, it’s just the fronts I’ll be doing - is the pedal feel the same ?

Also what’s the clearance like on the on the wheel face and inner diameter estimate in “mm”

Cheers

I am still using the stock 120i dust plates but I plan on upgrading that soon. I will try find the post where I posted pics of the caliper-rim spacing. Pedal feel is exactly the same. For the size of the calipers they are really light only difference you will notice is breaking distance will decrease. If you had to go with steel braided lines the pedal feel will be hard. Hope that helps. I will take pics of how the 120i dust cover looks with these rotors
