Emergency Brake

Post by AndreFordT » Wed Oct 20, 2021 12:19 am

Just need to repair the emergency brakes on a 1912 right hand drive (English) Touring.
Here is what I found. Watch the setup. It is strange. Was it after market? Or did someone a special build for this car?

I think it will end with a total rear axle rebuild. I found also left - right play on the shafts.

Andre.
Those are a aftermarket part designed to be adjustable from the outside by taking up the wedge instead of adjusting the brake rod keeping the propper lever angle. Judging by the silver metalic color of the grease your thrust babbitts have become liquid or you lost a bearing. I would suggest you replace the park brake linings, its near impossible to get the grease out of them. Good luck.

Craig,

I ordered at Langs a total brake rebuild kit.
Due to the play on the shafts and the grey color of the rear axle oil, I will take the rear axle apart for a total rebuild. Not cheap but the only way to do it right and keep the oil and grease off the brakes and leaking on the wheels.

I recently learned that inner axle seals should be installed with gear oil RTV. Other sealants are likely to leak.

Steve, that sealant is great for the housing and spool, but not so great for the modern inner seal as it doesn't adhere and harden. Ultra black seems to do better for the modern inner seal.

Well, now I don't know what to think. Stephen Heatherly told me that the gear oil sealant cured his leaking seals, while Ultra Black hasn't stopped mine.

In addition to the 2 seals on each side, I add another seal, which is altered, outboard of the inner bearing sleeve. The seal modification involves a notch cut into the OD of the seal. The notch is oriented so that is in the bottom position. This seal serves as a labyrinth. The notch allows any oil that gets past this seal to flow back to the center of the differential. I found that oil generally follows the OD of a rotating shaft.
After 3200 miles, my brakes are still dry.
