November - 2015: All the interior and engine bay had to be removed for the roll cage to fitted, So as part of the refit i decided to replace the standard booster/tandem master cylinder with a dual master cylinder and balance bar. I have used a Bicknell master cylinder and balance bar assembly which mounts at a 60deg angle to clear the strut tower. Fabrication of the mounting plate for the master cylinder and balance bar assembly is from 8mm 6061 aluminium.

October - 2017: Added an extra brace to the dual master cylinder mounts to help stop deflection of the firewall and the strut tower. Because of the staggered locations of the master cylinders, under heavy braking they push against the side of strut tower which bends out of the way. It also starts to push the fire wall inwards. Adding a brace from the fire wall to master cylinders removed most of the deflection and made the brake pedal a lot firmer.

October - 2012 : I finally found the time to remove the disabled ABS pump - Removal was the easy part - Re-plumbing the brake lines took a lot of time. The rear brake line was simple to refit as there is a joining block just under the steering column. The front brake lines were a bit more complex as a tee piece was required to join both left and right brake lines together. For the left front brake line I followed the original path along the top of the firewall and down the passenger side keeping the brake line as far away from the exhaust pipe as possible.

As most Japanese cars use the same type of brake lines, it was a case of go to the local wrecker and find brake lines of the required length. The replacement brake lines came from a Toyota Camry and the tee piece mounted on the booster came from a Hyundai Excel. ( See inset image )

Jul -2012 : The Nissan 200sx S15 single piston brake caliper & solid disk rotor rear brakes have been replaced with Nissan R33 GTST Skyline brake calipers and disk rotors. The Skyline has larger diameter ventilated disk rotors and 2 piston calipers. 

Unfortunately the Skyline uses a small internal drum brake for a hand brake. I have decided to go with in line hydraulic hand brake rather than mess around with drum brakes and hand brake cables

Oct 2013 : A slight upgrade to the front brakes has been made using the new Gktech adapters and Skyline R33 GTS-T aluminium calipers. The disk rotors were also replaced with a set of RDA grooved an dimpled versions.  This is a reasonably straight forward upgrade however there are two things to watch for.

#1. The difference in rotor diameter between the standard Nissan R33 GTS-T and the Brembo option rotors. The standard R33 STS-T disk rotor is 296mm in diameter where as the Brembo rotor is 324mm in diamter. This means the inner radius of the standard R33 calipers is too small and when first assembled the calipers will rub on the rotors. I made a cardboard template of the disk rotor and slowly reshaped the caliper using a die grinder.  

#2. The grooved and dimpled rotors are left and right handed. Take note of the labeling on the box as there is no markings on the actual rotors. If you forget there is an image on the RDA website showing the correct orientation.
