Brakes

PostBy: wilder11354 On: Tue Oct 08, 2013 7:54 pm

over heated the oliver1750's right brake last year towing the mower/conditioner 12 miles from house to farm. Didn't think much of it other than its not good, and worried about ruining friction discs. well this spring when i backed it out of barn, the right brake would grab pretty hard. Going foward it was fine. actuator plate setup use steel balls between 2 steel plates with ramps machined on insdie that balls sit in, and a series of springs to force balls back into deep end of ramp when brakes released. Guess i tempered the springs, and when i applied brakes the springs lost thier spring while hot. was kind of suspecting the springs were weak or ramps and balls weren't so good(worn) after i did al new discs a year before. Backwards the plates will open up, apply brake from fricttion of outer brake surfaces if springs aren't strong enough. So i broke down got the actuator assembly. set me back $170 with shipping. Luckily its an easy replacement. Three outter brake cover bolts, take off adjuster nut/locknut combination and it slides out easily. Will give the brake spur gear shaft seal a good eyeballing for any leaks. Then adjust and it should be good.

Here's the pics of the change out of actuator plate. Theres an inner brake disc, actuator plate, and outer brake disc. The outer cover is the outer friction surface for outer disc. both brake discs also friction off the actuator plate which is held stationary by 2 large lugs cast in brake housing itsel.

The wrenches are on the adjuster nut/locknuts. Need to drive tractor to do final adjustment. The old actuator plate definitely was not completely retracting on the ramps between, wether it be the balls worn or ramps bad, or spring tension gone.

Why,You Could Have Been One Of The Original"Little Rascals" ! Sure like like you put the heavy duty spank to that set-up ! It's one hell of a thing when you confirm your own suspicions,especially on something so important as brakes. You did really well to get this deal all smashed out now. You 'Da Man ! That's an interesting set-up. Thanx for the pics as I've led a sheltered life and haven't been a big tractor man and hadn't seen what you've shown before ! Thanx Wilder ! :up:

Backing up trctor that right brake would grab, i mean hard, lock up tire. Didn't want to keep using it that way and ruin that brake spur shaft/gear. if so that would have been a major tear apart of brake housing out of rear housing, and possibly top differential cover which is very time consuming. and many more systems components to disturb,seat, remote controls and linkages, PTO linkages, and a lot more part costs.(gaskets,o-rings, seals, hydraulic fluid, etc)

you might have only needed to re-lube,the heat might have burned off what had been doing the job,maybe not,but very possible

I have an Oliver 77 and I always thought that brakes on a tractor were an optional extra that I have no use for - those complicated double pedals. Olivers were incredibly well made tractors. At 35HP they were great pullers at shows in their class. Loading bars, lots of suitcase weights and go like hell - let something else stop me - brakes were redundant.

it's my impression that the separated brake pedals are to stop a spinning wheel that has lost traction and gain traction on the other wheel which it would not have because of the differential. Good to have.

seperated brake pedals are for first and foremost steering.

From the FORD PATENT US2540458 in 1954

Arranging the brakes for separate operation enables the brakes to be used not only for stopping but also to facilitate in turning the tractor. A much sharper turn can be made by applying the brake on one side of the tractor to retard or bring to a complete stop the corresponding driving wheel so that a turn can be made with the smallest possible radius. This is important in many tractor operations, as, for example, when the end of a furrow is reached in plowing and it is desired to make as sharp a turn as possible.

From the John Deere Patent US2821265 in 1953

The traction wheels are keyed to these axles and individual brake means, one for each Wheel, are utilized for facilitating steering of the tractor, since the brakes may be individually applied. It is conventional practice to locate the brake pedals or equivalent brake control members in close proximity to each other

A diff locking pedal is for getting unstuck...
Step on the pedal and put it in reverse...
to get out...
Rather than going forward and getting better stuck... ;)

use brakes while mowing with haybine on hills, speed i mow at am in 3rd gear underdrive most times, and it will free wheel while O/U drive is in U-drive while going down an incline.

Did the disassemble and clean thing 3 years ago on brake actuators, right side never was right before or after, Overheating it just finished it off i guess.

I don't think I could steer a tractor without individual wheel brakes. A lot of times when I am cutting wood, enough weight is of the front tires to make steering sluggish at best, and not at all, at worst. That is a problem when you are trying to negotiate around trees. Bush hogging and plowing are just a few other cases.

My father hates it and locks our brake pedals together, and is forever after me because I unlock them as I need to steer.

On our old Ford 900 without a posi-lock in the differential, braking the spinning wheel would sometimes work. It was a last resort and not all that effective, but it was better then nothing, and as I said, would sometimes work.

We have the same problem on our Kubota as the springs are weak on the right side. Overall though it sounds worse then it really is.

way overdue update, the actutor fixed it fine!! so nice to have smooth brakes, and no jerking binding popping noise in reverse. was concerned it would do other damage.
