1988 TII w/ 180k miles (rebuilt engine @ 177k)

So Im replacing all 4 of my rotors as well as the brake pads and the website Im buying them from suggest I replace my brake lines as well (since Im stock anyways)...

-How hard is it to do?

-Anyone have an online guide?

-Will I have to drain out the fluid in my master cylinder to do this?

-They recommend replacing the lines with stainless steel ones... Good idea?

_________________

They then list the stainless steal brake line parts down as

1986-88 RX-7 4 LUG
1986-88 RX-7 5 lug solid rear disc

-What do the lugs mean?
-How can I tell which one I have?
-Rear solid disc?

 

Changing the lines is not a bad idea on a 16 year old car. Not hard, but time consuming. Sometimes difficult to remove due to crud buildup. A flare nut wrench is desireable so as you don't round off the fittings. Standard rubber lines are sufficient, but the stainless steel lines are superior. Fluid will run out of the lines when removed (Good way to change fluid) and naturally the brakes will need to be bled.

 

Stainless steel brake lines are MUCH better for brake feel. I cant begin to describe the difference..

 

I havent done stainless steel lines on my RX-7, but I know when I did these on my dad's corvette he wouldnt stop raving about how fantastic they were.

I plan to go stainless myself, when I need to do my pads/rotors.

 

I purchased a set from another forum member. God they really are an improvment. Just be sure to use brake line wrenches or you'll round them rather quickly. Once they are on i poured in some superblue brake fluid and it's all good after that, Brake feel was 100% increase over stock. Also installed hawk pads at the same time.

P.S difficulty level is about 5 out of 10 to install them. And you "should" have another person help you bleed the system.

 

So can anyone tell me what the parts listing means?

 

what parts listing are you talking about?

i would say go with stainless steel lines as they do not cost that much, and are a nice upgrade. one thing i do when i work with a brake line is to take the little rubber cap off of the bleeder screw (if you still have it) and cap the exposed brake line with it to keep fluid from dripping everywhere.

 

 

lugs are the number of nuts that hold your wheel to your car. some rx7's have 4, some have 5.

you can easily tell by looking at your rims - do 4 nuts hold them on or 5

the rear solid disc refers to the brake rotor. some 7's had a vented rear rotor and some had a solid rear rotor. to check this you have to take off your wheel, and look at the edge of your brake rotor, if you don't see any holes, you have a solid one.

not trying to make you feel stupid, just answering your questions - we were all newbies at some point, right?

j.ho

 

4 calipers, 4 rotors, 4 speed bleeders (personaly i had issues with speedbleeder.com, they sent me the wrong ones after telling them what car i had. They ignored emails about it, so stuff them, I think nopistons.com has them in sets for less expensive anyhow)... 4 steel brake lines from mazdatrix, 2 rear steer eliminators.

HArdest part is the rear steer eliminators. Second was the stupid bolts that rounded off. In all though... the brake lines is probably the easiest part out of all of it...

 

Theres no offense taken by me at all... Really, I take more offensive to the people didnt answer my question in the first place... But Im not trippin one bit...

Anywho...

So if Im replacing my rotors as well then I could assume that they will be a solid rear disc since my car does have 5 lugs and they list a 5 lug as a solid rear anyways?

 

This is slightly off topic and i hope i don't hijack your thread but....when you switch to ss-braided brake lines, do they hook up to the stock system or do u have to mod stuff?

 

No solid rear disks on your car. You said you have an 88 TII. That means you have the upgraded brakes-- 5 lugs and vented rear rotors. Some RX-7s had 4 lugs with solid rear rotors and some had 5 lugs with solid rear rotors.

 

no, you don't have to mod. the stainless lines are a direct swap for the original rubber lines. just be sure to get the right set, since some FC's had more rubber line than others. 4 piston front brake FC's have a hardline that connects between the line and the caliper, where as single piston rotors are just the brake line, and the stainless lines for those will be longer.

the only FC's that came with solid rear discs are base models i believe. any of the ones with 4 piston calipers (vs single piston fronts in base models) have vented rear brakes. if you have a turbo, it should be vented.
