S13 180SX RHD Master Cylinder Upgrade? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

saiga488 · 11-12-2019, 08:04 AM

I am wanting to do the Evo 8/9 front brake caliper/rotor upgrade and it appears that most people recommend that I need to upgrade the master cylinder also. I see most people recommend the Z32 1-1/16 BMC. The problem is that all of the master cylinders that I find are all for left hand drive cars. I have a RHD 180sx car so the brake lines are on the opposite side. Any recommendations on which BMC to buy and where to buy it?

I did the z32 brake swap all around and used a 1" bore, for a 95 Nissan pathfinder. 1" bore to go with my manual brake booster. Can't say if they will line up with Factory hard lines, as I am using a chase bays oem relocation kit.. They come in different bore diameter with the ports on the correct side you need it on. Mine is a doorman part #m39976 with the factory nissan looking reservoir.

i paid less than 75$ for a NEW one, not re-manned.

check out this site for BMC size comparison...

having the outlet ports on the 'wrong side' and using banjo fittings will give you more clearance in the engine bay.

On a Lhd Bmc, I tried using the banjo fittings and there was no room for them or else I would have used my LHD BMC.

just find someone breaking a 300zx on ebay.co.uk or try garage-D in England.
