Break shoe width
I have a problem getting the correct torque on my rear hub.It binds at 40 ft lbs. I also see signs of hub to shoe interference. My shoe width measures 1 5/8". Do you feel that is correct?
Should I grind off the high spots , replace the shoes, or is there something else I am missing? These are hydro brakes. Thanks Lee |

Re: Break shoe width
On my juice brakes I had to put axle shims on the rear. Snyders catalog says prevents the brake drum from rubbing against the backing plate

Re: Break shoe width
Yes, you'll need to put shims at the outer ends of the axles. You can buy or make your own out of a tin can or whatever else is around. Re-torque the nut once or twice after a few miles. For those who are building a rear end that will have hydraulics or later mechanicals, I recommend machining .100" off the housing flange where the backers bolt to. This moves the brakes inboard and eliminates the need for shims.

Re: Break shoe width
I decided to order the shims. They are .004 thick. Does anyone know how to calculate the amount that will bring out the hub? Assume a 5* taper. My trig is a little rusty.
Thanks Lee |

Re: Break shoe width
I would be very concerned about your not being able to properly torque the axle nut and would solve that problem asap. Look closely at the axle shaft threads. Buy new HARDENED nuts. Brattons has them.
