Rear Big Brake Kit==Help

speedjunkie · 12-01-2010, 10:06 AM

^Do you have a write-up on how you did that? I was looking to swap mine but I knew I had to make some new lines and I don't really need it yet on stock brakes so I just waited. But if I could work it like you did I might replace it sooner.

I don't think it will make sense to make it as a kit, just because so many different rotor diameters will be to much work/money to make the necessary offset bracket for every set up were demand will be so low. If some one wants a kit i can make it at the same time i make mine.

I will post some pics for you in a couple of days. I have machined a couple of 969 master to make it more fd rx7 friendly install. I have one on my bench for custo, will post pics when done machining it.

Thanks! I might be interested in one of those e-brake setups too, even though I don't have aftermarket brakes yet haha.

Write up for the 929 master cylinder: http://robrobinette.com/mastercylinder929.htm

The write up is about 10 years old, so the prices have prob. changed.

As I said before, there is a good chance that even with upgraded brakes you won't need this. I didn't on my silver track FD with upgraded brakes all around. If your pedal is soft, I'd highly encourage you to do a full bleed before trying this... it may not be necessary.

David, I do remember your brakes were soft at RA, but I also remember there was some kind of obstruction in the lines going to the rears that was preventing fluid from flowing to them. Did you ever figure that out? I'd start there if not.

If I remember correctly, you can buy a master cylinder rebuild kit for the stock FD master cylinder from the local parts stores as well.... AND it replaces the stock plastic plunger(which is a point of failure) with a metal one.

Which 14 in rotor did you go with? Is the slight thickness difference of the rotor make any difference?

I'm also interested in the 969 MC. David Garfinkle was going to make one for me but slightly difference in design on the new ones prohibited from him making me one.

Thanks Brent. Yeah I cleaned and rebuilt all the calipers. Replaced front rotors and pads. Need to do rear rotors and pads. I guess I need to get a pressure tester and see what I have at the rear calipers. Do you happen to know what they put out in stock form? Ever tested that?

I really just want to make sure I am not overworking the fronts. Unbalancing the car under braking etc. The pedal to me still feels like I am having to go too far into the stroke before real things start happening. I'll grab the rebuild kit and start there. Not out of the question considering it is original M/C.

14 inch willow. The thickness will not be an issue, the hand brake caliper can be set up for any thickness disk.

Here are some pics of re worked 929 MC

The re worked 929 MC now has 3 outlets 2 separate dedicated for the front and one dedicated to the rear.
All 3 take banjo style fittings. No more leaking flared fittings. Etc...

Chip, is your 929 MC drop in? If so, what would be the cost for one?

Yes the master is a drop in to a certain extent.
Are you still running the ABS? If so the 3 banjo outlet 929 is not going to work for you .
With abs the 2 banjo outlets will work best.
New 929 master machined to take banjo fitting with pre made line. 220.00 shipped

Let me know if you want one so i can send you a invoice
