Bah!, what a bad day. I when to take the car to test but just like the previous owner told me it will fail cause most rx7 will fail it. I guess, he is right since he is a machanic. So, now I have to spend $150.00 on repair to take the emission test again soon. It sucks cause is costing me alot at first.

Not to meantion I have to get that Brake Master Cilinder replace whihc a machanic told me that are rotary engineers that is cost $219 with out the labor work added up to it which will be around $334.00.

Man, if anyone here that live in the NW knows how to install that I would be glad to buy the part online or somewere as long as is cheaper than $219 and pay ya to install it for me. Unless is not so hard.

What is going on is that when I take my car from the parking break off and I press on the break it go all the way down. I even have to pump it a few times to get it to stop. So, I was told that cold be a bit more than just the Master Cilinder. Who knows...

What ya think?

I dont think brake master cylinders are that much. Check autozone.com

Do I need the;

MASTER CYLINDER (BRAKE SYSTEM) for a
1981 MAZDA RX7
WITH 4 WHEEL DISC BRAKES
* FENCO_REMAN, or CARDONE

or

CARDONE W/O MASTER CYLINDER

or

ARI W/O MASTER CYLINDER

I am not sure

I replaced my master cylinder only to find it was leaking calipers, so check them first.

Have you bled the brakes??? That'll cause mushy brakes.

A brake master cylinder lists at $80 for an '81 at Victoria British. You just have to check if you have rear disc brakes.

DJAngelicon

yea, some places ask me if I have rear disc brakes. I am not sure how to tell. LOL!

However; I am trying to decide weather to give the tune-up or fix the break problems first?

Any ways, if someone have a post in how to find out and to check the break system would be great because the previous owner told me I need a Master Cilinder because it have a leak somewere. Every 2 weeks or so he have to put break fluid. That is what he told me so not sure.

What is your trim?

Only GSL and GSL-SE have rear disc brakes, unless it was retrofitted. You could try to take a peek inside the wheel to see if you can glimpse brake parts. Maybe a picture would help?

I replaced my brake master from mazdatrix for about $110. It was a really easy job.

I just posted my pictures here.

Looks like you have front disc/rear drum. Easiest way to tell is to look through the spokes on the wheel, if the fronts and the backs look the same then you have 4 wheel disc, if they look different you have rear drums.

DJAngelicon

ok going to check right now brb.

RotaryRyan

from the looks of the pics, i think you have rear drums.

DJAngelicon

Ok the front I can see the break pads and the back, I can't is like is cover maybe that is the drum you are talking about.

comradegiant

That is the case for sure. So you will be looking for parts for front disc/rear drum.

DJAngelicon

Ok cool now to figure out if is going to be expensive or not

Welcome to the world of rx7's. First thing to do is completley inspect the brake system for leaks. this means pulling the drums and making sure the wheel cylinders are not leaking. checking all hose and front calipers for leakage. From what you are describing is the master cylinder is leaking, but never jump to conclusions. As a no brainer, fixing the brakes is #1 always. As far as the smog is concerned, what numbers do you have for the idle hc and 2500hc. Hydrocarbons.
I also strongly recommend that you invest in an repair manual for your vehicle and start educating yourself or you will need a second job for repairs. The vehicle is pretty straight forward and you can learn all of these things as you go, rx7doctor

DJAngelicon

Oh Cool Great! thanks for the advice. I will do that so, for now I failed on my Emession Test this ares;

Cruise Limit: HC (PPM) = 180 | CO (%) = 1.3
Cruise Emission: HC (PPM) = 571 | CO (%) = 3.08
Cruise Result: HC (PPM) = Fail | CO (%) = Fail
ldle Limit: HC (PPM) = 220 | CO (%) =1.2
ldle Emissions: HC (PPM) = 997 | CO (%) = 6.11
ldle Result: HC (PPM) = Fail | CO (%) = Fail



That is what I see on the Vehicle Inspection Report. Everything else have a number or a N/A. Also some other numbers but just gave you the one that said fail on that collum so that you can see what numbers were there and what areas did failed at.

Looks like your cat is deceased, second make sure your plugs and wires are in good shape, make sure that the air filter is clean .Spray around for any vacuum leaks, correct any found.
If the oil has not been changed in awhile, change it. Run some strong carb cleaner thru the tank, if you can find bg's 44k, get that, if not find redlines complete fuel system cleaner and run either one thru a 1/2 tank or less making sure it is concentrated as much as possible.

Will a Tune-up for the car will do at the shop? I know the computer check up is $89.00 here in Seattle and then any work is added up to it. The papers say to have at least $150.00 on repair on the car before taking the emission test again.

jays83gsl

What? They put a limit on how much you have to spend?

Ghettoe. I could do all that stuff myself. Why pay someone else to do it?

That's horrible. Move to New Mexico, we don't have emissions laws in the "Land of Enchantment"

DJAngelicon

LOL! I agree jays83gsl. Well, in the papers say for any vechile 1981 and over have to spend in repairs after failing a emission test no less than $150.00. After that, once you have done that the second emission test is free. First of all the first emission test was $15.00 which now I am $15.00 less than I did and soon going to spend more money in a tune-up. Man, just the computer check-up cost $89.00 dollars. All that keep adding up, even though I got a great car for a amazing price I am still spending more money as it is. Suck big time!...

jays83gsl

Um, what does a computer check up do? I'm not used to these mechanic shop terms

DJAngelicon

Well, This so called Machine Shop Analyzer or however you spell that. It suppost to check everything on your car. From line presure, exhaust, gas, rpm etc.... Just to check why I failed the Emission test. Pretty much this is Tune-up or repair by someone that is Certified as a Emission Tester at a Machanic Shop. Then he gives me the papers so I can go back to the testing place and test the car again.

It sound like a pain in the a$$... I have never done this before and this is all new to me. lol Never in my life. So, wtf. lol

Felgar

I dunno man, I think you have a better chance learning this stuff and doing it yourself than having a shop do it. Brakes may be a different story cause you're life depends on them, but all the vacuum lines, etc. and the tune-up, I think you can do it better than anyone else. These cars a pretty unique and most shops don't even know how they work...

So I'd hold off on that computer crap for now. Spend your money on the tune-up parts (plugs, etc.) and on the brakes. And also you may need to buy a cat converter to pass the emission which can be pretty steep. Don't spend your money on some "mechanic" who doesn't know what he's doing, unless you don't have the time to try doing it yourself. Just my $0.02...

Before you do stuff just post on here what you're trying to do and make clear that you're knew to this work and people around here will help you out.

Tip #1: When changing spark plugs only change 1 at a time to avoid screwing up the plug wires.
