| - 6 - brakes only, that this occurs and as we are still using the same brakes, there is no reason for this to be different. If there is a tendency for the steering to pull to the right, it will be due to the brakes on the right hand-side of the car being more powerful than the left. Likewise, if the steering pulls to the left, it means that the left-hand brakes will be powerful. This can only be corrected by attention to the brakes themselves, after, of course, seeing that the equaliser is working freely. Care should be taken when fitting up the front axle and springs that the spring clips and spring sheath are bedded and are properly tightened. As the torque of the front braking is taken on these parts it is very much more important than on the 40/50 HP. car with the rear brakes. If there is a complaint of the steering taking charge on corners, the pivot lean should first of all be taken up because with continual front braking, it is possible for the pivot lean to alter owing to deflections on parts fixing the front springs or the front springs themselves. It should be firmly borne in mind, that we do not expect equal braking on all four wheels - if a car has equal braking, it is wrong and will be likely to give very much more trouble than one on which the front brakes are ineffective. The front braking should always be kept down as much as possible. | ||
