Converting 6" mechanical brakes to hydraulic (not going to 9" but keeping the 6" drums)

Robert Connearney
 

The old Fiestas were 4-lug, but I think are typical Brit Ford 4.25" bolt circle. The most common 4" 4-lug discs/drums/hubs are Sprite/Midget/Vega/Monza (and Buick/Olds/Pontiac siblings). Other 4-lug with larger bolt circle brakes can be redrilled, if you have a trusty machinist. As I've posted here on previous occasions, an acquaintance had a race car with Crosley running gear; turned the Crosley rear hubs to remove the drum, bolted on Monza drums on the Crosley drum wheel lugs. Can't recall if he also used Monza backing plates, as would be necessary if the Monza drum diameter were different. The incentive for this was to allow brake inspection/servicing possible without needing to carry a hub-puller. The car's original 9" brakes were otherwise adequate.

If I needed to find a solution to this conundrum, I'd check to see which of the fore-mentioned discs were readily usable, and I'd find some suitable motorcycle calipers, I'd make caliper brackets, and then I would market them.

Austin Healy Sprite were 4 bolts on 4” circle same as Crosley.  The Sprites had 4 wheel hydraulic brakes with disc on front.

Thanks

Checked Amazon for 1978 to 1980 Ford Fiesta disc brake parts. The pictures seem to show five bolt rotors. Guess they could be drilled for Crosley four bolt.

Picking up on Tim's hope to find an original disc brake set up. Does anyone have possibilities for modern disc brakes that would adapt to fit a Crosley?

I have rebuilt the complete system (mechanical) on my 49 and they might do but I am exploring possibilities. Truthfully I may end up finding a complete disc brake system and rebuilding it for my 49.9" Bendix are getting rare as hen's teeth because everyone has the same idea. I'm looking at options that may help future Crosley guys and  gals.

Been gone on vacation, but do have a wheel cylinder mounted on each type of mechanical backing plate. I'll try to get some pics up soon.The bleed valve on the Mini cylinders is at an angle and would not work. I took them out and blocked the hole.I'll have to use the brake hoses the disc brakes use and bleed them that way.

Mike Mayberry
 

Any more progress????

Tim Hamblen
 

These are 5/8 bore. I believe some OEM Coopers were 1/2 ". These are not OEM but aftermarket . I got them from Moss Motors, they had the OEM type but they are much more $$$$

Mike Mayberry
 

What are the measurements of the wheel cyls? I assume the 3/4 is the bore. Solving this would be great for everyone with 6in brakes!!!

To add more noise to the 6" hydraulic story, Dave Edwards sent me the following photos. "Bud" Wachholz in Columbus OH, a race car builder & parts supplier, also made a 6" conversion. Dave has two different castings from Wachholz, the top one is on the backing plate shown in the second  photo, both are 3/4". Dave also said the Ryan's (the ad I posted earlier) were brass & the Wachholz are both cast iron.

Year ago I had CD wagon with Stude brakes, I think all 4 wheels. I bought it and flipped it when I was 18. Never did a think to it but save it from a junk yard and haul it home. Don't remember the big bucks I made but I would guess maybe $25-50.

I have looking at trailer axle parts that have 7" hydraulic drum and 4" bolt circle.

RockAuto shows a 4 bolt rotor.  Still some drilling may be required to fit a 4 inch bolt pattern.

Should I admit that was 45 years ago?  Allowing for inflation + increased rarity + increased demand + the salesman skills of Mr. Anspach…  I would think you could ask more.  I sold the 6 inch hydraulic conversion set for $250 – no axles, just backing plate, shoes, and wheel cylinders.  And that was in 2010 at Wauseon.  Your discs should be worth considerably more than those.

How long ago Steve?  I have a set to sell (could bring to Hershey) but don't know how to price it.
