In continuation of "Just a quick Brake Job..... (and not to hijack that thread)", and response to boxy02.
Regarding ALIGNMENT
A few snapshots when dialing in this kart.
Tool. Rudimentary. Worked well. Repeatable.
24 x 12 ceramic tiles. True enough.
15 degree layout. Two sides. Caster swing-out.
Camber zero'ing.
Note: diagonal was sufficient.
Caster input, plus Camber measure - typical tool orient.
Shim stackup. Various thicknesses.
Toe setup.
Results:
Arrived at +9 degrees caster left and right. + 1 degree camber left and right. Opted for 1/4 inch total toe-in.
Rear unloaded + 1 degree camber.
Rear unloaded 0 - 1/16 total toe-in.
Please don't ask how many times the wheels came off to allow re-shimming (smile).
Did not use all slotted shims, instead got proficient enough to swap shims in 5 minutes. Wheel on,
wheel off. Gotta admit a total stack of all slotted shims would have made it slightly easier. The steel flat washers
to within a couple of thousandths surface profile made great shimstock.
One tip. Keep a light jack under the spring end held tight before releasing the arm from the chassis mounts.
This prevents the spring from sagging a few inches and having to jack it up every time to remount the bar.
