Upgrading Brakes from Hayes to Brembo

[john_kattenhorn]

Hi,

I've had the parts for a while but I've been rationing the good projects over the lockdown weekends;

I'm currently waiting for a spindle key to drop the front wheel out but here's my progress so far.

Looks nice!

Why dont you re-use OE liquid reservoir ? Brembo one looks hideous.

What calipers are you going to install ?

That?s one clean garage! Have you had problems with the oe callipers leaking?

+1, garage looks great!

What bar ends are those by the way?

They are from R&G with some crash protection in the end

No I've not seen the leaking problem from these calipers (or the ones on my R1250GSA), I've heard lot's of people having these issues though.

I'll definitely compare the OE reservoir vs. the Brembo - I've not had the chance to compare them yet.

Here is a picture of the calipers - they are GP4-MS Monoblock nickel plated.

Nice upgrade, what needs to change out of interest, do you need any spacers for the callipers and is it a 17RCS or 19RCS ?
Thinking of doing something similar.

Nothing. you just need to remove dowel pins and that's it.

from photo it looks like 19rcs corsa

Seems the GP4-MS are 30mm pistons like the M50 should be 17RCS. But they will work on the 19RCS using the 18 setting.

yeah I think 19RCS corsa corta is 18 by 20 with additional adjuster.

anyway, 3k gbp BOOM, brakes are upgraded, no leaks guaranteed

GP4-RX have 32/34 which works on 19RCS.
