1PWRFULH,I have just finished the second brake job on H's in the last five months. The job will go fairly smoothly as long as nothing is siezed. Remove the brake pans(covers) and undo the bolts holding the drums in place. Gently persuasion should slide them off. ( two screw drivers a small pry bar). Once slid off you have the main task of getting the old seals out. Some suggest drilling two small holes to insert metal screws but I don't like the idea of filings around the bearing. I use picking chisels and try to cave the seal housing in towards the centre and after chiseling and picking with the pliers you will get lucky and pull what is left of the seal out. be careful not to get into the bearing or burr the shaft. Wipe clean. Your new seals are about half the width of the old ones. Here is where I disagree with some fellow rebuilders. I replace with one new seal while some maintain that two are needed. I trust the new technology that goes into the seal, after all we are replacing felt and leather! The new seal can be placed so it misses the groove created by the old seal on the drum flange. My I-H dealer who has been at it for 60 years says to place the seal flush with the tractor and reassemble. Now I understand why guys figure two seals are a guarantee but these seals cost me over $30 a pair and I don't like doubling my repair cost. So far neither of my H's have shown any sign of leaks and my brakes slide the rear wheels. When you reassemble you brakes , loosen the jam nut at the bottom of the pan and turn the bolt in as far as it goes( it won't go all the way in..just in tight) and then turn it off 1\2 to 3\4 and tighten the jam nut. Your brakes are adjusted on the brake clevis on each side.Remove the pin at the top and turn the clevis shaft either in or out to make the adjustment Adjust so you have slightly more than an inch of pedal play. Also adjust so both pedals have the same tension at the same spot so they will work together and one not pull over the other That's about it for the brake seals and adjustment.There should be brass bushings on the brake band lever end ...they may be stuck in the tractor at any rate they should be there...so good luck with the seals and brakes from Mike in Exeter Ontario
