I used the scott cylenders because i did not have to do any welding or add any thing to the air frame so if i want to put it back to original by putting the old brakes back on airplane I can, also it helped when the faa inspector saw that no airframe mods were done all bolt on it helped with sign off also all my parts were used on certified air craft . KEEP IT SIMPLE !!!!!!! less then 30 days start to finish Chuck

Chuck.

My installation is actually simple to. It uses the pulley attachment brackets, for the brake cables, to hold one end of the master cylinder the other end is attached to the brake pedals via two links, no welding no drilling. However, the parts that hold the cylinders have to be manufactured.
If I can figure out how to pull crop a picture from a email I will post it.

a cleveland master part #10-17 is a pull type master could mount them in the pulley that leads the cable out to the gear and hook the cable to a forked end on the cylinder and pull it with the cable

The grove cylinder is a pull type also, part #681-1, I just use the links instead of the cable between the cylinder and brake pedals.

Re: Grove disk brake conversion for tapered axls

hi tribe

weather has let up so we got airplane out and did taxi test on new brake system bottom line it will hold the plane at full throttle 2000 rpm static with 74/43 prop. They feel grate not at all grabby have good feeling will stop airplane from fast taxi in short order, Ground handling was improved tight turns can recover easy back to straight with out any trouble CAN'T ASK FOR ANY THING BETTER CHUCK

Re: Grove disk brake conversion for tapered axls

You will like the Grove master Cylinders a bit better I think. I just sold my Baby Ace that had the Scott Cylinders with Grove Disk brakes...all works well only problem with the Scott Cylinders is that as the Disks wear it is imperative that you keep pumping fluid into the system else you will lose the brake... its the Scott Cylinders not the Grove system that causes the issue.. not a problem really. I flew the Ace 165 hours in two years and only had to fill it up(from the bottom) once. The Scott Cylinders are a simple affair.. consist of a diaphragm and piston..no real reservoir as my mechanic explained to me anyhow. No flames intended here. Just explaining my mileage on a plane I rebuilt completely to new specs.

Hey Tribe,

UPDATE

Well it's done I have my sign offs from my AI, and the originals are off to FSDO in Oklahoma. I'm posting a copy of the 337 front and back for you guys to use if needed, and I sent a copy of my full paper work in a e-mail to Robert Lees to post. If anyone is needing documentation and need copies of any of this just ask I'll e-mail it to you as long as you can receive files that are 17.6 MB.

Have a great day guys

How much weight did the brake mod add?

Re: Grove disk brake conversion for tapered axls

Richard

The Grove wheels and brakes weigh 9.20 lbs times 2 equals 18.40 lbs. The Scott masters weigh 21 oz. times two equals 2.56 lbs. for a total 20.96 lbs. 2lbs for hoses for a total of 22.96 lbs. The Shinn wheels were 5 lbs each total 10 lbs the brake assemblies were 2.5 lbs each for a total of 5 lbs. cables, pulleys, pedals, cable clamps, 3 lbs for a total 18 lbs. ( 22.96 minus 18.00 equals 4.96 lbs. more than the Shinns were.)

Re: Grove disk brake conversion for tapered axls

Chuck has very kindly offered to share his 337 with the Taylorcraft tribe.

His 337 is on the Foundation Technical Resources page here...(scroll down to 337 Data, and look under "Wheels, Tyres, Gear, Skis & Floats"

A direct link to his 337 is here (It's an 18Mb pdf).

Just as a reminder, I periodically update the Technical Resources page from many generous folks on this Forum, so take a look every so often.

Finished all the work on plane yesterday and got to fly it for the first time today did a few full stop landings to see how well it stops. Well the first landing on pavement 60 mph approach 3 point landing STOPPED in less then 400 ft. with not a lot of pressure on the pedals.That was first landing the brakes just made a good short field airplane in to a grate short field airplane.Stopped straight handled well on the ground after my test flight Shannon resumed her flight training with 5 more landings with out any problems worked well Chuck
