items needed:
929 master cylinder
1 or 2 12 inch brake lines with metric inverted flare
10mm flare nut wrench
14mm flare nut wrench
12mm wrench
philips head screw driver
first you should put rags beneath your master cylinder because you dont want to drip brake fluid on any of your paint. then remove the brake lines going to the top of the brass fitting, remove the line going for the hydraulic clutch, disconnect the fluid level sensor.
then remove the 12mm nuts holding the m/c to the booster. now you can remove the m/c from the car. once removed remove the screw that holds the reservior on the m/c, and put the reservior onto the 929 m/c.
here you can either use two custom brake lines or you can use one custom line and the rear brake line off the rx7's m/c. i took off the brake line from the back of the rx7s m/c and used it for the front line on the 929s m/c. if you use the brake line from the rx7s m/c use new washers with the banjo bolt. then i made a custom line for the back. i got my brake line from a local auto parts store for $5 with fittings on it already. i just had to bend the line. torque the brake lines 10-15 ft-lbs
connect the lines to the brass fitting
now you should bench bleed the m/c. if you dont do this you may never be able to get all the air out. after you bench bleed the m/c its time to install it on the car. it goes on the same as the rx7 one so theres nothing tricky
once its on its time to bleed the system.
my initial impressions: i love it! im using the stock brakes, and they feel so much better. i havn't tried anything too highspeed yet, as i want to make sure the lines wont fail on me first. i've done a lot of stops from about 50mph, activated the abs a few times, and the pedal feels great. less travel, and a firmer pedal. you dont even notice the extra pedal effort.
