Mazda’s version of the 924/944

Was the RX-7 utilizing a rotary engine. The cars are actually quite fun to drive and were pretty popular. A freind of mine brought over his son’s TX-7 Turbo II (now don’t get excited, that doesn’t mean twin turbos) so we could put in a new brake master cylinder. It had started to puke fluid everywhere, so a replacement was needed. Oreilly’s was able to order us the part, and it was definitely not “porsche pricing.”

A little wet and rusty looking, I wasn’t sure what we were in store for. Luckily… appears brake fluid must also act as a lubricant as everything came apart pretty easily.

Old MC out. Yuck.

New MC installed and the reservoir back on. Bleeding a new MC can take awhile, even with an initial bench bleed. Luckily all the bleed screws on the caliper were easy to open, so a couple rounds of air bleeding, and it was ready to go. We discovered it also needs a new clutch, so we will tackle that at a later date.
