Car Tuning Braking System Upgrades Questions and Answers

Question 1

A customer wants to upgrade their daily driven vehicle's brake lines for a firmer pedal feel and improved responsiveness. Which upgrade is most appropriate for achieving this?

Accepted Answer

Replacing rubber hoses with stainless steel braided lines.

Answer

Installing larger diameter solid steel lines.

Answer

Using softer compound rubber hoses.

Answer

Switching to a higher viscosity brake fluid.

Question 2

When upgrading brake pads for frequent high-performance driving or track use, which compound characteristic is MOST important for preventing a loss of braking power during repeated hard stops?

Accepted Answer

High resistance to brake fade at elevated temperatures.

Answer

Low noise and dust production.

Answer

High coefficient of friction at cold temperatures.

Answer

A soft compound for quick bedding-in.

Question 3
