I am repeating myself from a previous post but again it is relevant to this post as well.
Quote:
For a static assembly (not taking into account suspension motion) and constant pressure of brake fluid, brake performance depends primarily on these items -
1. Caliper piston area
2. Pad friction material area
3. Coefficient of friction of pad material within a temperature range
4. Effective clamping diameter of the friction material
5. Type of disc material.
6. Temperatures of disc and pads.
These are the basic items that determine braking performance.
Dodgeman said the brakes will either lock the wheels or they will not! This is a basic quality assessment of performance. For his needs this is the most basic requirement of his braking system. (They work or they dont!). I assume that he also requires that the braking be controllable.
L18-B110's points are also qualitiative, as the main consideration is how well the braking performance can be controlled without locking the wheels and for how many applications.
In my opinion and this is not by any means complete, things that help control braking quality are : -
A. Cylinder size ratios between master cylinder and caliper pistons, Boosted or unboosted.
B. Brake pedal leverage ratio of pivot to pedal and pivot to clevis pin.
C Brake pad material composition,
D Disc material and friction surface (slotted etc)
E. Effective temperature range of friction material.
F Ratio of pad clamp diameter to wheel rolling diameter.
G Degree of cooling provided to rotor by venting or ducted air.
I'm sure there are plenty more things I have forgotten, that others can add.
