Disc Brake Conversion
Posted by: Klipo89 ()

Thinking of converting front brakes to disc from an S10, what needs to be done?

I will be purchasing this bracket

Why not use one of the kits from Clarks Corvair?

Cheaper? Why do you feel the need for them? Corvairs brake very well with original brakes.
Parts needed, but not all inclusive; caliper brackets, calipers, rotors, hoses, brake pads, master cylinder, proportioning valve, longer lug studs. Start adding them up.

You will need a pair of S10 4WD front rotors, longer grade 8 bolts for the steering arms, a pair of bolts for the large upper holes and the hubs need the outer diameter turned down so the rotors will slip over the Corvair hubs.
I did the conversion on a friend's car using the Scarebird brackets.
Scarebird varies which calipers he recommends, i.e. S10 2wd fronts or Celebrity fronts.
You may have to hunt for the correct length hoses.
Make sure you get the brackets pictured as Scarebird made some where the caliper mounted too high and hit the A-frame in hard turns.

Photo from a road test back in the day.

Notice how front and back wheels are stopping the car beautifully with large drum brakes.

Remember - Racing Stingers used stock drum brakes!! (upgraded shoes)

Scarebird will send an instruction sheet with your order. Requires some machining
of your hubs. You will need to buy rotors, calipers, and brake pads. (2 and 4wd Chevy S-10 parts) Also you will need new brake hoses and a new Master brake cylinder and maybe a proportioning valve. they recommend 1975-77 Monte Carlo MC,
a S-10 was used on mine. I have the Word file, but I cannot attach it. Anyone who
wants it, PM me with your direct Email address.

The only thing I can add is that front disc brakes are not as sensitive to water as drums are. Driving through a puddle and hitting the brakes with drums can result in the drum brake pull.

drum brakes are also subject to "fade" - this is caused by the drum expanding as it heats up- it can reach the point where the brakes cease to function, especially on long stretches, like going down a long downslope. i think having a manual trans with drum brakes makes sense, because you can use engine braking for long slopes.

I put disc on the front of my Corsa and love it! I got S-10 rotors with 25,000 miles on them from a crashed 4x4 from my local Junk yard for $5 ea and new flaps calipers and steel braided hoses and it stops WAY better, Over 100 mph with the drums they would heat up and fade fast then do nothing! The disc's stop straight and true consistently every time and never fade, all my vairs will get disc's from now onthumbs up

I have slightly modified Scarebird front brackets, S10 4WD rotors and aftermarket aluminum calipers (replacements for the GM "Metric" calipers) on the race car. Michael LeVeque also has brackets for the GM Metric Calipers, and the aftermarket replacements.

I did the scarebird brackets with wilwood calipers, 70's c10 master cylinder, and braided steel lines. It brakes about the same as stock but doesn't pull to one side or the other under heavy braking like my drums did. And no fade!

I would recommend a 7/8 bore master with the metric GM caliper. Mike

I also did the Scarebird conversion, comes with a required parts list. Got it all at Autozone. Got my dual master cylinder from Clarks with the lines to go from single to dual, it tied in nice with the disc conversion, and from my experience so far no proportioning valve needed.

Also had to change my lug bolts. The rotor is a little thicker where it goes over the hub than the drum and I was not comfortable there was enough thread length left when I put my lug nuts on.

Oh yeah I forgot about the wheel studs. The scarebird instructions give a napa part number for a longer stud which I bought but the holes in the hub are too small and have to be enlarged for them to fit. I had the machine shop do that along with the turning of the hubs. The brackets also have to be trimmed slightly if you want to use wilwood gm metric calipers(even though they are supposed to be a drop in replacement for the s10 caliper used with the scarebird brackets).

I have Scarebird brackets, S10 slotted rotors & calipers for sale and can machine your hubs if needed. I went to bigger rotors.
PM me if interested.
