Mazda 2: Brake Fluid
BRAKE FLUID INSPECTION
1. Verify that the brake fluid level in the reserve tank is between the MAX
and MIN marks.

- If the brake fluid level is below the MIN mark, add brake fluid.
BRAKE FLUID AIR BLEEDING
CAUTION:
- Keep the fluid level in the reservoir at 3/4 full or more during the air
bleeding.
- Be careful not to spill brake fluid on any painted surfaces. Rinse off
any spilled brake
fluid with water.
- Begin air bleeding with the brake equipment that is furthest from the
master cylinder.
Specified fluid
- SAE J1703 or FMVSS116 DOT-3
1. Remove the bleeder cap on the brake caliper or wheel cylinder, and attach
a vinyl tube to
the bleeder screw.
2. Place the other end of the vinyl tube in a clear container and fill the
container with fluid
during air bleeding.
3. Working with two people, one should pump the brake pedal several times and
depress and
hold the pedal down.
4. While one technician depresses the brake pedal, another technician loosens
the bleeder
screw using any commercially available flare nut wrench, drain out any fluid
containing air
bubbles, and then tighten the bleeder screw.

Tightening Torque
- Front: 6.9-9.8 N*m {71-99 kgf*cm, 62-86 in*lbf}
- Rear: 6.9-8.8 N*m {71-89 kgf*cm, 62-77 in*lbf}
5. Repeat Steps 3 and 4 until no air bubbles are seen.
6. Perform air bleeding in the order of the procedure described above for all
brake calipers or
wheel cylinders.
7. After air bleeding, inspect the following:
- Brake operation
- Fluid leak(s)
- Fluid level (See BRAKE FLUID INSPECTION).
VACUUM LINE INSPECTION
1. Remove the vacumn hose. (See VACUUM HOSE REMOVAL/INSTALLATION).

2. Verify that air flows through to the intake manifold side when blown by
mouth from the
vacumn hose of the power brake unit, and that air does not flow through to the
power brake
unit when blown in the opposite direction from the intake manifold.
- If there is any malfunction in the inner area of the check valve,
replace it
together with the vacuum hose as a single unit.
3. Install the vacumn hose. (See VACUUM HOSE REMOVAL/INSTALLATION).
VACUUM HOSE REMOVAL/INSTALLATION
1. Remove in the order indicated in the table.
2. Install in the reverse order of removal.
