Wow, what a kick-off into the rotary hobby - an 85SE!

For your information, you have a couple of awesome things going for you in that car that I feel compelled to tell you about before talking about your brake MC issues;

1) the 1985 models were the last of the 1st Generation cars, and as such, pull a premium since they were the epitome of the body style. All the minor improvements made by Mazda in the 'early-years' made it onto the 1985 models, which leads to...

2) your model is a GSL-SE - the top of the line. You couldn't get a rotary powered car in 1985 with more power, more luxury items, and more pizaz than the GSL-SE model! You are the proud new owner of the top model in it's day, the epitome of the RX7 at that time, and a dream to drive.

Excuse me while I step off of my soapbox here, but you should take really good care of that car going forward - it's a great starter vehicle and some of the upgrades that your car has compared to the other models are;

1) Electronic Fuel Injection - technical, RE-EGI (Rotary Engine - Electronic Gasoline Injection), complete with Dynamic Effect Intake for that 'natural supercharger' effect,
2) '6'-port induction - the 'Variable Valve Timing' of it's day, designed to increase low-end torque and ALSO increase high-end power by opening up 2 extra intake paths during high horsepower conditions
3) Power everything!
4) Sunroof, standard!
5) Power steering, in some models, along with optional leather interior,
6) Clarion Radio/Tape/EQ which was decent for it's day,
7) Lowered ride height springs, 14x5.5" aluminum wheels w/Pirelli P6 tires (back in 1985), with the attractive and easy to find bolt pattern of 4x114.3 for aftermarket wheels!
8) Lowered rear trailing link mounts to help control oversteer,
9) body fit bumpers (compared to 79/80 'SA' cars), and brake cooling ducts,
10) 9.9" front and 10.2" rear VENTED brake rotors all around - 4 wheel disks, and a Limited Slip Differential (LSD) for 2-wheeled smokey burnout excitement!

If it's in good shape, that car is a winner. I think the other guys here will agree that giving you the impression of what you have is my attempt to help you understand that you have a RESPONSIBILITY to take good car of that car! Drive it fast, but carefully. Take care of her, and she'll take care of you (you HAVE named her, right?!?).

Onto the brakes: Your Master Cylinder (MC) looks like this:


Part # 43-4000-FA66 $116.82 at Mazdatrix (www.mazdatrix.com), but may be cheaper at Victoria British (www.victoriabritish.com) - get used to using these sites, they are great for finding parts for our cars at competitive prices. Mazdatrix is a discount dealership for Mazda, VB is simply a parts house.

Replacement of this part is very straightforward, you'll just need a 14mm boxend wrench, a 10mm open-end (for the hardline fittings), and some time. Bleeding the brakes is an artform, but easily done once you get the hang of it. You'll have to bleed all 4 corners since you have 4-wheel disks, but it's not hard - search these forums for the info.

Good luck, welcome to the forum, and post back here for more assistance - there are a bunch of us SE owners that love to know that there are others out there like us that continue to baby the EFI cars. Take care,
