Many people think that if you choose a larger bore size master cylinder, you will generate more hydraulic pressure. But in reality, this is not the case.
The master cylinder bore size has a significant effect on braking performance. Some adjustment in its diameter affects how the pedal feels to you and how much pressure you apply.
1. Excessive bore size will create a very hard pedal that requires more initiative to push the pedal. It will also provide tight travel, indicating that the pedals won't move any further to generate enough braking power. Due to the high drag, you may end up with a jittery vehicle where you will have to hit the brakes so hard that the brakes engage too quickly.
2. The bore size is very small, it will have a gentle pedal, which requires minimal force to push. It also results in longer travel where the brakes have to be squeezed down to generate stopping power. So there will be less tension on the brakes, but you have to push down harder for the pads to work. This is not a good option if you are stuck in traffic or need to stop quickly.
So it is very important to have the correct bore size of the master cylinder
If you're wondering what happens to the master cylinder when you press the pedal, consider the following:
v · First, a push rod will be used to drive the main piston, which will compress the brake fluid in its switch.
v · Hydraulic pressure in the cylinder and brake lines increases as the main piston moves.
v · The auxiliary piston will then be driven by this pressure, which will cause the brake fluid to condense in its circuit.
v · When brake fluid flows through the brake lines, the brake mechanism will be activated.
