This law requires vehicles first registered in California after January 1, 1940, to have power brakes if they weigh more than 14,000 pounds. However, vehicles weighing less than 18,000 pounds are allowed to use two-stage hydraulic actuators instead of power brakes to improve braking effectiveness.

This law requires all passenger vehicles made and first registered after January 1, 1973 (excluding motorcycles), to have an emergency brake system. This system must be designed so that if a single part of the regular brake system fails (unless it's a structural part of the brake master cylinder body or effectiveness indicator), the brakes will still function when you keep pressing the brake pedal.

This law outlines the braking requirements for trailers and semitrailers. If the trailer was made after January 1, 1940, weighs 6,000 pounds or more, and goes 20 mph or faster, it must have brakes. Trailers made after January 1, 1966, weighing 3,000 pounds or more, need brakes on at least two wheels. Those made after January 1, 1982, with air brakes should have brakes on all wheels. The brakes must work with the towing vehicle's brakes to meet certain stopping requirements. However, trailers supporting equipment like a crane's boom or mast are exempt from these rules.

If you have a trailer coach or camp trailer that weighs 1,500 pounds or more (excluding passengers), it must have brakes on at least two of its wheels. These brakes should work well with the towing vehicle's brakes to ensure the vehicle combination can stop within the legal distance.

This law specifies that trailers and semitrailers made after the end of 1955, which require brakes, must have power brakes that automatically engage if they become disconnected from the towing vehicle. These brakes should hold the trailers still for at least 15 minutes. Additionally, trucks and truck tractors made after 1955 must have service brakes that can stop the vehicle if the trailer or vehicle being towed breaks away while driving.

This law allows an auxiliary dolly or tow dolly to have brakes installed if desired. It's not a requirement but an option available to users or owners of these devices.

This law states that any forklift truck made after January 1, 1970, can only be towed behind another vehicle if it has brakes on the rear wheels. These brakes must work in addition to the towing vehicle's brakes to ensure both vehicles can stop within a required distance.

This law states that all motor vehicles must have brakes on every wheel that touches the road, but there are some exceptions. Older trucks and truck tractors made before July 25, 1980, don't need front wheel brakes unless they have multiple steering axles. Vehicles from prior to 1930, certain older truck tractors, motorbikes made before 1966, and motorcycle sidecars also have exceptions. Additionally, buses and large trucks can have a system to reduce front wheel braking on slippery roads. All these vehicles must still meet specific stopping distance rules.
