Phosphor bronze bias bar in aluminium pedal?

[motorsportbeng]

I'm designing my own pedal box for my track car and have bought a universal brake bias balance bar, a spherical bearing type in what looks to be a phosphor bronze outer shell. The kit came with it's own weld in steel tube for the pedal but I want to run aluminium pedals. Materials wasn't a subject I particularly excelled at at uni so was wondering if anyone could shed any light! With a liberal coating of teflon spray will the bearing move ok inside a hard anodised aluminium pedal or is the softer aluminium going to cause problems? I could always design the pedal to have the steel insert press fitted in but wanted to avoid this extra process if possible.

Cheers
