I had to jury rig a longer bracket on the wheel since the axle I installed is 3" longer than the old one was.
Most of us have done that.
Only thing I didn't do was bleed the lsv.
The LSPV is the seconded highest componet in the system. That is why you bleed it last, Air travels up in the system
The e-brake isn't too big of a deal though, as I also have a line lock I'll be installing, IF I ever find fittings to get me to 1/8" pipe threads, lol.
Line locks are not a legal e-brake, but good for short term use. You can also get adapters to take it from metric to SAE. Try adjusting the brake shoes up tighter and adjust the cable on the bell crank for the e-brake. With the extensions on the e-brakes the handle has to pull futher to set the e-brakes.
