Brake Pedal
The brake pedal is an interface of the brake system. The user's pedaling force is amplified at a lever ratio to control the brake amount of the brake. In addition to weight reduction and improvement of operation feeling, we design and develop new structures for the future by ourselves.
Roles of Brake Pedal
The brake pedal has mainly 2 roles:
(1) Transmission of Pedaling Force
The brake pedal transmits a pedaling force to the master cylinder and ensures a braking force of the vehicle according to the pedaling amount.
(2) Amplification of Pedaling Force at Lever Ratio
The brake pedal amplifies a pedaling force using a lever ratio as shown in the figure (the principle of leverage) so as to stop a heavy vehicle with human power.
Types of brake pedals
There are 2 kinds of brake pedals designed by us, that is, a single-type brake pedal and a link-type brake pedal.
The single-type brake pedal has just one pedal arm and the lever ratio during operation is constant.
The link-type brake pedal has 2 pedal arms coupled to each other using mechanical linkage. The lever ratio can be changed according to the amount of pedaling and has an effect of improving pedal feel.

Link Type
Comparison of Single Type and Link Type
In addition, as the single-type brake pedal, there is a hollow sheet-metal pedal aiming to be the lightest in weight, instead of a general thick plate pedal.
The hollow sheet-metal pedal is a pedal having reduced weight while maintaining the rigidity by bonding two sheet metal stampings by plasma welding to obtain a hollow structure.

Clutch Pedal
The clutch pedal is a pedal for manually performing ON/OFF operations for the connection between the engine and the transmission gear at the time of speed change in a manual transmission (MT) car. In addition, its arm part may be made of resin instead of steel plate, so it contributes to weight reduction.

Parking Brake / Vertical-pull Parking Brake
The parking brake is a part for stopping a vehicle at the time of parking. In recent years, the motorization of the parking brake has been accelerated. On the other hand, there are still manual hand-type parking levers for trucks and sports cars. The vertical-pull parking brake is disposed in a vertical (longitudinal) direction between the steering and the shift with focus on sports travelling, instead of being generally disposed in a horizontal direction in the vicinity of the console next to the driver. The vertical-pull parking brake was developed by pursuing an appropriate position during sports travelling, and was mounted for the first time on the "GR YARIS". It was unveiled for the very first time to the public in the Tokyo Auto Salon 2024, and became a big topic on social networking services.
