Brake set-up

[ultimaandy]

Any idea's on how to optimise the front rear brake bias.

My can-am's braking has been tranformed by some uneducated tweeking , I now want to do it properly without writing the car off in the process.

Suggest you start with the theory to get it in the right ball park, and then find somewhere safe to fine-tune it. You need to get the static balance right i.e. under light braking are the brakes balanced, and then get the dynamic balance right (under heavy braking the load on the front brakes should increase more than on the rear). Static balance is determined by the caliper size and geometry, plus the brake balance bar if you have one. Dynamic balance is determined by the rear pressure limiter valve.

Don't be a skin flint, buy a Bias Gauge, and find out what the balance is. Ps. does it go fast enough to need the brakes, it's only a American speed.

The best way I've found to pre-adjust bias is the way Carrol Smith recommends.
: jack up all 4 wheels
: one person rotates front wheel, one person is gradually applying brake until front wheel can not be rotated.
: holding that brake pressure, rear wheel should JUST be able to be rotated using same amount of force that was used to lock front wheel.
: Adjust bias until you achieve this condition.
For the wet I like to start with both wheels locking at the same pressure. Count the clicks, or rotations of the bias dial to know where to set the bias for each condition.
For snow, put the car in the garage, and apply parking brake.
