Table 3: \(p\)-values for multiple (two-sided) comparisons; age, mileage, capacity. The highest average front brake force was noted for Ford cars at 6.8 kN (1.8), while the lowest was recorded for Fiat cars at 5.2 kN (1.9) (Figure 4). Similarly, the rear brake force (Figure 5) was highest for Ford cars at 2.0 kN (0.7) and lowest, mirroring the front brakes, for Fiat cars at 1.3 kN (0.8). The situation was analogous for the parking brake. Statistically significant differences were observed between brands. Table 5 summarizes the variance in braking between the wheels on the front axle and the rear axle. The allowable difference in braking force for wheels on one axle is a maximum of 30% (Figure 6). It can be observed that, in the case of the front axle brakes, significant differences in braking power occur in isolated cases. On the rear axle, such instances are more numerous.
