Yeah i know – the pace is quite slow lately, but im still working on the project silently in the background. But today is the day i have som GREAT news for you. I got a Package delivered from Japan with some parts i’ve been looking for over two years now until i recently stumbled across them finally 🙂
I’m talking about the Sumitomo MK63 brakes. But what’s so rare about them you might ask? they pop up every now and then on the internet. But this is not your standard MK63 for vented disk, but the very rare first gen. version for OEM Nissan disks, which are FIA homologated and were used in various ex works racing cars. I’ve even been told that nissan asked them back after the races from their teams.. wow 🙂
Here’s a comparison between the standard brake (Also sumitomo manufactured) and the MK63:
I plan to restore / rebuild the new brakes before they go in.
EDIT: Someone asked for the weights difference between the OEM and the MK63 caliper so i put them on the scale for him and was quite surprised the MK63 is even lighter than the chunky two-pot calipers 🙂
MK63 Solid disk type including brake-pads: 4.300 Kgs
Standard two pot calipers including brake-pads: 4.445 Kgs
And here’s some specs from the NISMO homepage and the old Datsun performance catalogue:
Later NISMO offered the same brakes under their brand but they’re obsolete since a few years..
Oh and while ordering parts from japan anyway i decided to order all available maintenance and refurbishing parts for the brakes from the NISMO / Nissan catalogue and got them delivered from a local Nissan dealership from Yokohama 🙂
