Brake pedals - Drum vs Disc

Post by tomkidd »

After having issue with the brakes on the mini and using a pedal box from a drum braked mini, some people suggested that the pedal arms are different.

Its a long shot but does anyone have one from a disc and a drum braked mini to compare? I wan't to see if they are different...

the disc one does make a huge difference when used over the drum one

a cheap trick is just to get one from a mid 1980s car and cut the pedal pad bit down to match the early clutch

I'd confirm what rich says above, you just can't get a decent feel to the brakes with a drum brake pedal. Even with 4 pots.

A disc-brake pedal is also thicker... about 1,5-2 mm thicker I think.

So... this may solve my brake issues.

I'm currently using a drum pedal and my brakes barely scraped through the MOT due to the amount of travel.
I'll swap to a disc pedal and see if it improves

I have got a drum one on my cooper s brake setup

passed the mot fine, brakes don't feel bad, nowhere near what you get in modern cars but stops just fine

I do want to put a s pedal in mine (hence my wanted ad) wasn't sure if it would make much difference but at least it would be the correct part

As did mine, but and it's a BIG but. When it came to actually stopping down my favourite mini road it ass a different matter. First of all cooper S disks and pads, shite, then Cooper S brakes and black stuff pads, still shite, Minispares 4 pots and black stuff pads, then green stuff pads still shite.

Then a brake though ;) talked to rich and fitted the brake pedal off of the girlfriends C-reg mini, much to her annoyance. Fixed proble with the brakes and proper brakes that will actually stop you all the time.

Just compare it to a clutch pedal... if it's visibly thicker then it's a disc pedal.

I've got unservoed s disks with a drum pedal and they are fine. They are your textbook mini brakes in fact.

Ditto, bog std S discs and cylinders, no servo, drum type pedal and mine lock up with reasonable right foot effort. If you can get your car to lock up, how much more do you need ?? I've just hammered it round Aintree, absolutely flat out and very heavy on the brakes. No problemo.

The angle on the pedal cannot possible alter the "feel" or the "effort" The only thing that can, is the length between the two holes, clevis pin-> brake pedal shaft, and the length of the pedal itself.

ive always thought that the cooper s pedal was angled so that when its pressed and its working, its at the right height for 'heel & toeing'

if you use a drum brake pedal its further down, so its harder to dance the pedals

I also use one foot on both pedals and it's fine.

Perhaps it has been swapped.
