turbo 2 brakes
 

i am getting the respeed front brake adaptor for tubo 2 brakes on an fb
my question is has anyone done all 4 brakes from a turbo 2 on an fb rear included. i have a fabricator making rear brackets for me. its going in a 84 gs

the question i have is do i need the turbo 2 master cylinder, brake booster, proportioning valve?

If you get the GSL-SE rear brakes, you'll have virtually the same thing, no fabrication required. I compared the two setups many years ago, and if memory serves me right, the rotors, pads, and caliper bore were identical between the -SE and the FC.

I've seen pics of a FB with TII brakes all around, not sure about the MC or anything else.

i have a ford 9" rear the gsl-se brakes are actually harder to fab a mount for

i may just get a proportioning valve from the fc

I have 10.5" Ford rear brakes on mine, with 310mm Wilwood in the front. I'm using the FC master cylinder and booster, it has a 15/16" bore and a much larger booster. You need to mount it with a 10mm spacer on the firewall, but all the bolts are in the same place. You will definitely need to swap the master cylinder if you're using FC front brakes.

Feel free to PM me if you need help, I've spent months getting this right.

yea i bought the turbo 2 master cylinder, and propotioning valve today. what kind of spacer did you use
do you have a pic?
thanks

Nah it's all bolted up and hidden.

If you can picture the back of the booster with four long studs that go into the firewall, I simply used some 10mm box section steel and created a square spacer that connects all the studs.

I guess a more professional way would be to get a slab of 10mm thick alloy and cut the centre out, but my way works and is cheap.

You will also need to grind a small amount of material out of the clutch master cylinder as it will hit the new booster. I understand this is all you need to do with LHD cars, but as mine is RHD I also needed to slot the master cylinder holes on the firewall a small amount. I'm not sure why RHD has less tolerace than LHD, guess only Mazda knows that ;)

I am replacing my rear 4-Piston calipers, with TII rear brakes rotors and calipers. I am using a 94? Mazda 929 Master Cylinder with No ABS.
It is a larger Master than the TII or the FD.

I putting the smaller brakes to lower pedal travel, and regain my parking brake that I lost when I swapped the Ford rear in.

Absolutely correct, the 929 has a 1" bore instead of the 15/16" in the TII.

I've been told that the TII unit I have will be "borderline" in terms of pedal travel, but worst case scenario I'll do exactly as you're planning and swap in a 929/Cosmo unit.

thats why im adapting the turbo 2 rear setups to the 9 inch, it wont be that bad
i have a turbo 2 mc and p-valve so the brakes will balance

the booster in the fc and fb are the same part numbers so the mc should be a bolt in swap but ill have to witness that when i get to that point i guess

the 929 unit is a direct bolt in in fd's i believe what about fb's

i should be fine with the turbo 2 mc and turbo 2 brakes all the way around, the way i look at it.

I understand the 929 master will bolt up to a FD booster, I don't know about FC. It is definitely different to the FB.

I can assure you the FC booster I have is completely different to the FB unit. The only similarity is the stud pattern where it bolts up to the firewall, the rod length and diameter of the booster is very different.

Im also running a TII booster and MC.The booster bolts right up if you use 2 of the factory aluminum spacers under it.Then you have to grind a little material off the side of the clutch master for clearance.
I run 12" front discs with TII calipers from Selectmaz and stock SE rear brakes.

yea i just double checked, and i made a mistake they are different part numbers,
SOMETIMES I ACTUALLY DO MAKE A MISTAKE, go figure

i have an auto so the clutch master doesnt exsist
thanks for yalls help

and i just bought the turbo 2 booster also

I am running an N/A FC Booster - because the TII was too large.

That's what I will end up with in a month or so..

Although I have to modify them to fit my rear.

so the na booster is smaller, i guess that would also make the brake pedal a little stiffer.

i know the gxl and the verts come with the turbo 2 brakes, thats why i was asking and i figured they would be the same.

yo wattup ?
how muche the sport prakes sistem if I want buy't from U.S.A becous am from Saudia Arabia ???

thanks...

what sport brakes?
we are talkin about puttin turbo 2 brakes on an fb.

I now am just asken aboaut the brakes becous am all reday make the turbo 2 brakes in my baby becous it's now 700 RWHP , OK ...

ThAnKs ... :)

how about some grammer lessons. and about cost i have no idea. it will probably cost you more than the brakes are worth to get them to you.
mainly if you are truely making 700rwhp you need more than turbo 2 brakes.

yes of cours I thinkin about HKS praks of Toyota sopra if i swap't in my baby , what do thenk ?

I think that if English is your first language, you have some serious issues.

am sorrey .. I'll fix it ........ yes of cours I thinkin about HKS brakes of Toyota supra if i make't in my baby , what do u think ?

i hope if you makin babies they come out more gramatically correct than you.

You would have too do more fabrication but I guess it could work!

thanks . . .
;)

What's with all the grammar police? His spelling may not be correct, but at least you can figure out what he's saying. He's from another friggin' country for Pete's sake! Cut him a little slack and remember he's trying to save another 7....:)

Are you referring to it's physical size and general mounting problems, or that it made the pedal too light?

saudiarx7 - Don't be concerned about people who criticize your English. There are some very ignorant, uneducated jerks on this forum, and I am sure your English is much better than their Farsi, Arabic, or whatever.

monster7 - There is also some serious misinformation on here, and I hate to think of people going to a lot of trouble for no reason. I put 2nd gen 5-bolt hubs and brakes on the front and rear of my 1984 GSL, and they work VERY WELL with the stock 1984 master cylinder and booster. Until you try that and are not happy with it, don't waste your time changing master cylinders.

Look at this thread, my posts number 5 and number 13.

If you have any other questions about my installation, send me a PM.

My understanding is that all 5 bolt 2nd gen cars use the same brakes. If anyone here thinks that is not the case, post the caliper part numbers so we will all be educated.

Thanks guys .. but I take't so easy dont worrey

Thanks agan . . .
;)

thanks for that info, one of the most logical i have ever got on this site.
the reason is i think i need the fc stuff, i have a gs not a gsl or -se. the drum brake p-valve has a check valve as all drum brakes require. and if you just put disk in the place it will mess up the front to rear balance. I could have of found a gsl or -se mc and p-valve and used that. ah oh well ill figure something out. this car is goin to have more fabrication in it than i care to think about already.

I totally agree, it seems that the stock m/c and booster would probably be sufficient for FC brakes front and rear, but as I'm using significantly larger brakes than that, my comments reflect the research I've done on using a larger m/c and booster. There is no way I could use the stock FB unit with the brakes I have.
