CONVENTIONAL BRAKE SYSTEM [(E)]
id041100200199
Outline
• A brake pedal with an anti-intrusion mechanism has been adopted. As a result, driver safety has been improved.
• A vacuum pump has been adopted, improving braking force.(without Mazda M Hybrid system)
• A large diameter, ventilated disc-type front brake has been adopted, improving braking force.
• A large diameter, solid disc-type rear brake has been adopted, improving braking force.

Master Cylinder
Without Mazda M Hybrid system
-
Purpose/function
-
• With the adoption of the master cylinder having an enlarged diameter (22.22 mm {0.8748 in}), brake pedal operability has been improved.
• The diameter of the pipe between the master cylinder and the DSC HU/CM has been increased, improving response during DSC operation.
-
Construction
-
• Except for the cap and brake fluid reserve tank, the master cylinder cannot be disassembled. Therefore, if there is any malfunction in the interior of the master cylinder, replace the cylinder component without disassembling.
L.H.D.
R.H.D.
-
Operation
-
• When the brake pedal is depressed, the push rod of the power brake unit presses in the master cylinder piston. By pressing in the piston, pressure is applied to the brake fluid to operate the brakes.
Power Brake Unit
Without Mazda M Hybrid system
-
Purpose/function
-
• A 10 -inch, single diaphragm type power brake unit has been adopted, achieving compatibility between high braking performance and excellent brake feeling.
-
Construction
-
• Except for the fork and locknut, the power brake unit cannot be disassembled. Therefore, if there is any malfunction in the power brake unit, replace the power brake unit without disassembling.

-
Operation
-
• The depression force of the brake pedal is increased using the vacuum from the vacuum pump, and the force is transmitted to the master cylinder.
Front Brake (Disc)
Purpose/function
-
Without Mazda M Hybrid system
-
• Chinese specs., European (L.H.D. U.K.) specs.or SKYACTIV-G 2.5
-
― Large diameter, ventilated disc type front brakes with a 295 mm {11.6 in} diameter and 25 mm {0.98 in} thickness have been adopted, improving braking force and fade resistance.
• Except Chinese specs., European (L.H.D. U.K.) specs.or SKYACTIV-G 2.5
-
― Large diameter, ventilated disc type front brakes with a 280 mm {11.0 in} diameter and 25 mm {0.98 in} thickness have been adopted, improving braking force and fade resistance.

Construction
Operation
-
• When brake fluid is applied, the piston equipped on one side of the caliper is pushed out and the brake pad is pushed against the disc plate. At the same time, the caliper body moves in the direction opposite of the direction in which the piston is pushed out so as to push the brake pad on the other side and generate brake force.
Rear Brake (Disc)
Purpose/function
-
• Large diameter, solid-disc type rear brakes with a 265 mm {10.4 in} diameter and 9 mm {0.4 in} thickness have been adopted, improving braking force and fade resistance.
• A brake caliper with an integrated motor has been adopted which enables brake force for hydraulic brake system or the electric parking brake.
