Why is it so difficult to start the brakes in cold weather?

Anti-freezing measures should be taken when vehicles are parked for a long time in winter, and the coolant level should be kept within the normal range. Recently, however, some friends reported that the coolant of their vehicles is normal, but the brakes will be hard at the start of cold car in winter, so why is the brakes so hard at the beginning of cold weather?

Why did you brake so hard in the cold weather at first?

It is normal for the brake to harden after the cold car starts in winter. The general reason is that the fluidity of brake oil will get worse when it meets low temperature, so it will thicken. When the brake oil thickens, the resistance of the brake pad driven by the brake oil will increase, and the natural brake will be harder than usual. When this happens, we only need to start the engine for ten minutes, and with the help of the heat of the engine, the brake oil can be restored to the normal working temperature, so that it can be used normally. Emergency braking may also be a real air booster failure, which affects braking without assistance or frequent braking.

Is it normal not to step on the first brake in winter?

This is normal. The reason is that the fluidity of brake oil becomes worse in winter. This situation can only be solved after the vehicle is completely warmed up. If we suddenly can't step on the brakes while driving, then we need to use the engine brake to slow down, and then try to use the hand brake. After stopping at the roadside, notify the trailer for rescue as soon as possible.

Can the brake stroke be adjusted?

The brake pedal has free travel clearance, mostly around 15-20mm, but most of them do not need to be adjusted by themselves. In the case of each maintenance, the staff will replace the exhaust and adjust the free stroke to maintain the brakes according to the wear degree of the brake pads. At ordinary times, we should also regularly maintain the wear of brake pads, so as to ensure our driving safety.
