Title: Fitting r32 Brake MC
Post by: bazmk5 on December 07, 2019, 11:52:05 pm
Has anyone upgraded to the 23.81mm brake MC?

I recently fitted R32 front and rear brakes and im having more travel in the brake pedal. I suspect its the smaller 22mm MC to blame for this and Im considering upgrading to the 23.81mm.

Has anyone done this? is there much involved?

Not sure what year your car is however mine (07 chassis registered in Aug 06) already has the larger MC fitted. Have a look to see if it has 23 stamped on it.  Is however inevitable that you will get more pedal travel having fitted calipers with larger pistons all round.

I would suggest re-bleeding the brakes first. When I upgraded to r32 fronts I didnt notice any difference apart from much better braking

As above, probably a bit of air on the system.   When properly bled, the first cm of pedal travel is a touch softer than the standard brakes but otherwise should feel a lot stronger.

Did you get this sorted @bazmk5 (https://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=37600) ?

I replaced mine with R32 rears and Mk7 Golf R fronts on a 22mm MC (I'm a TDI) and after a few bleeds the brake feel was OEM but with extra Gs :)

So as @Pudding (https://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10733) said, it's unlikely the MC is to blame.

I think only the TTRS/RS3 got a substantially bigger MC (much bigger calipers) at 25.something mm.  Even MK7s still use the same 23mm size as found in the ED30/late GTI, so regular S3/7R/R32 sized brakes shouldn't have a squidgy pedal.
