I'll just leave this here.  Time to get one of these in a car and do some road testing.



Scott, please tell me you already have a hand brake in, since my car won't drive quite yet.

Pics of the backside when you get a chance?

I'd like to see clearances. 

Do you take the E-brake stuff off the second caliper? or leave it on?

I still need like everything. I wasnt sure how I was gonna mount them or who was gonna make brackets. Then you were a boss and figured out both!  ;D thanks buddy. If I get mine in before you get your car running we can test it in mine  8)

Will do.  Both calipers clear tho the top (most likely gonna be hydro) sits super close to the spring.  It should clear fine, but running the e-beake cable to that caliper might be tricky.  The front caliper would be best for foot brake and e-brake cables since its pretty close to stock location.

As of now both calipers have the ebrake assembly on, since I'm still going to use these on my white car with stock setup.  So once I get my other calipers in, I will remove those assemblies and have even more room.

I'll get some pictures up either tonight or tomorrow morning since I'm at work till 11:00 tonight.


 Already got some rough estimates on CAD art and machining, gotta look into powder coat after I get a little further.  I'm thinking Super Neon Pink, not that you really see anything once it's all bolted up.


What I'll do is I'll just put these on the white car, hook up one caliper at a time and road test them.

I wont be using the ebrake cable stuff so there will be even more room. I will start acquiring the rest of the stuff needed soon  ;D

You NEED a cable ebrake regardless of hydro or not.  At least if you are worried about passing tech...., and parking.

Really... I have never had a ebrake in my current corolla. I don't care to have one but if I can't pass tech that changes things. I always have passed tech in the past, so is that something you have seen people fail tech for? I never put a stock ebrake setup on because I always planned on upgrading to hydro handbrake.

It's cause FIR tech is a joke.  But if you ever plan on doing more than D&D I suggest putting cables in.   I haven't seen it personally, but I have heard of it happening.  Hydro brakes don't lock in place....  So I would want one simply for parking.

Plus with bondurant taking over west I wouldn't be suppressed to see tech get a little more strict, which, would I kinda hope is the case

Can't you put a locking mechanism on the hydro lever?

I like David's setup because his brake lever is like 3 ft long. 

There is no power assist on the 2nd brake.

I'm sure you can pull back much harder than you can pull up.

Yes you can, or jam something in it to keep it pulled back.  But I still plan on having the stock cable setup just for parking.

I don't like the stock location because you have to reach around the seat which is a little awkward to get leverage.  Where as mine I just pull towards my chest.

Dark and not final, but this is a sneak peak of the CAD design.





huge thanks to Twincharger and his neighbor Josh for the help.

 I think it needs more beef. I realize the stock bracket is 1/8 metal but it also has the lip for ridgness. If my thinking is right its no different then how a dimple die works.

I know what you mean, and it's been brought up a couple times.  However I think the stock one is way over engineered.


Here is my thought process, feel free to correct me.  The caliper pinches the rotor, and therefore the rotor will "hold" the caliper center.  The caliper pinches, it doesn't Push or pull.  The rotor will naturally center the caliper as braking force is applied. 

Rotational force however, is what the bracket will experience most of, and in great forces.  Which I think the design will easily tackle.  As far as horizontal force, I don't see it bending 1/4" steel.  Only the mounting locations are 1/8" to keep factory alignment, the bulk of it is twice as thick as the stock bracket.

I will be mounting these on my white car and digging the brakes hard and see if I have any issues
