Hello, new to this site but glad to find it.
Im completing a 9 inch drum to scarebird disc conversion. This is what has happened and what is going on: The kit comes with a bracket to hold the caliper, and template for modifying the rotors. The parts are essentiallychevrolet S-10 calipers,rotors,pads, and hoses. Problem one is the brake hoses specced out were too short. This was easily corrected with a phone call and new p/n resulted in longer hoses. Im still not crazy about the way the hoses route, however, I believe they should work.Problem no.2: I carefully adapted the rotors with provided templates
and was not satified with the way they bolted over the spindles,after some additional reaming I believe the set up should work. Finally I needed to convert from factory 14x6 wheels to Chrysler 15x6 ralleyes.
This was a welcomed conversion that I had wanted to do and figured into my cost and they look great. Finally i used the master cylinder from a manual disc brake equipped car same vintage. Will bleed the system and road test soon. In fairness to Scarebird this is a 3 year old system which has been sitting on my shelf waiting for the install. It is my understanding that the newer systems have been refined and deficiencys addressed.
I will post with results.

Welcome to the Board. Thanks for the feedback on the Scarebird conversion. Please keep us posted. If you can get pictures they are most helpful.

I have a manual master cylinder for a disk/drum set up from Master Power brakes. It is new in the box. I never used it as I changed to rear disks and the aluminum MP master cylinder. Are you interested in this? I would sell it cheap. It was about $90 new, and would sell it for about half that. I suppose eventually I would have a need for it, but I don't know what the shelf life is on these things, and hate to see it just sit. PM me if you are interested. Good luck, and keep us informed.

Thanks for the offer on the master cylinder,but i already installed the recommended manual master cylinder, but i will keep it in mind if this doesnt work out. I wont get to road test the conversion for about another two weeks as the wheels i ordered are back ordered and wont ship until the 29th. Gives me time to do the other maintenance, and ignition upgrade though.

Russ

Good enough.

I did this conversion a few months back.

I had to clearance the brackets for the calipers to fit without "sticking". I had a machine shop do the bolt pattern for me on the rotors. I did have to "space" the bracket so the rotor would center up on the caliper, less than .100".

I just recently added a 75 Valiant master (manual brakes disk/drums) and have a booster I got from a board member, I did have a 72 manual MC. The brakes on the car now are just amazing! No huge effort on the pedal for the wife now and the car just stops very quickly!

Im glad to here the good words about the Scarebird conversion as this is the conversion that Im contemplating using on my daughters 72 Valiant but I will be using the 10 inch drum spindles so I can mount the caliper to the rear to clear the swaybar.

Hi,

I bought a 2013 year set for 9" brakes for my valiant -67

It's new kit with previa rotors and celebrity calibers..

Turned out I had 10" brakes . Tried to contact scarebird about differences and got no answer. Since price is the same was just wondering should I order a new set from overseas (takes 2 weeks)

Well turns out that the spindle is centered also with 10" brakes using the two lower bolts. Only 2 upper bracket bolt holes were not in line..I welded them and bored new holes accordingly to the spindle. Little DIY but works...upper holes did not fit the bracket surface 100% but 80% is enough. (One side is little bit open on bores because they are on the edge.)

I'll bet the only difference between the 2 kits are the upper holes location and center bore diameter.

Now, this should have the same dimensions than with 9" brakes since the hole is centered on the spindle/axle BUT then the problems came.

I bought Cardone calibers 16-4195 etc. Local store did not carry others.

Calibers sit too low on the rotors like said earlier too.. should have been spaced about 0.1" towards the outer edge.

BUT then these calibers WON'T FIT 14" rims!!!

Just hoping I don't get issues with pads inner surface to hit the rotors. It's a CLOSE call. Well, we can always grind some more.. ugh..

I Had to grind the outer edge 0.1" of the calibers and off course the inner cast piece off to fit these "properly" inside 14" rims.. REALLY tight.. should have taken some off the spindle cast piece also.

BUT still I was having issues.. rotors would hit in 1 place to the caliber from inside since the cast is not so uniform! This is not an easy place to grind off material!!!

I have been battling with this set a lot and I can tell you I'm not a newbie.

Also I had to grind some material off from the brackets to fit the calibers so they don't stick.

So a little disappointed. Not a bolt on!!! Nowhere near that!!

Designing/fitting this set to take 14" rims was the reason I think it's so DIY oriented!!!

Production Tolerances have not been taken into account and they will sure need some work!!!! No matter what parts you use!!! Castings change! Moldings change, rotors change!! Even with same manufacturers over time!

How come OEM's can fit to the original product? Tolerances have been addressed!!

So every time you change something, expect to grind some from somewhere?? hopefully not.

Also over time the calibers moves..hopefully I don't get any contact between parts and have to grind some again.

Now, I go and finish this install from hell and grind the insides and hopefully they work while driving... and won't stick. Countless fitting, parting, grinding, fitting, grinding, ouch.

Can't mount the calibers to the rear, they will hit lower balljoint cast piece extension (steering ball joint) and some parts of the spindle.

Saddles move inwards when pads wear.

Lastly would say to Scarebird, answer your mails and add some tolerances to your product(s) to make installing these a little bit easier.

Also had to file some material off from centering rings. They are laser cut and have to be filed where the laser has stopped cutting.

Be sure to measure the diameter on both edges and install with the bigger diameter inwards. Will help some to get them over the spindles. Not a biggie tho.

Laser cuts always with a angle.
