its easy going back to my formula ford days where i learnt this:-
Jack all four wheels of the car off the ground.
Have a helper apply the brakes for you.
Get them to gently apply the brakes whilst you spin the front wheel by hand. Keep applying brakes until the wheel just lock (ie you can no longer turn the wheel by hand anymore).
Check the other front wheel has got the same pressure. If you can turn it your caplier needs attention.
right if thats ok then go to the rear wheels.
On a normal road car, braking is around 80% front and 20% to the rear. So the rear wheels should turn. The percentage bias depends greatly on the suspension setup on the car, the softer the setup the less bias to the rear, conversely the harder the setup go to the rear more in the dry. On an open wheeler in the dry we try and get it 55% front 45% rear (in the wet we set up 45% front 55% rear!!). so in a race car (tin top) which has alot more weight transfer over the front, youd want around 65% front 35% rear. You can feel this with spinning the rear wheel. Get you helper to adjust the bias controller accordingly.
Anyway thats how we do it.
A much more accurate way is to have gauges setup in your brakes lines. When you get it on the road you will have to fine tune for your driving style.
