CAUTION:
•Avoid mixing brake fluid of different brands to prevent
fluid performance from degrading.
•When filling with brake fluid, be careful not to allow any
dust to enter the reservoir.
•Use new SUBARU genuine brake fluid when replacing
or refilling the fluid.

6. Rear Disc Rotor
A: REMOVAL
1) Lift-up the vehicle, and then remove the rear
wheels.
2) Release the parking brake.
3) Remove the two mounting bolts, and remove the
rear disc brake assembly.
4) Suspend the rear disk brake assembly so that
the hose is not stretched.
5) Remove the rear disk brake rotor.
NOTE:
If the disc rotor is difficult to remove, try the follow-
ing two methods in order.
(1) Turn the adjusting screw using a flat tip
screwdriver until the brake shoe moves ade-
quately away from the disc rotor.
(2) If it is difficult to remove the disc rotor from
the hub, drive an 8 mm bolt into the threads B of
the rotor, then remove the rotor.
B: INSTALLATION
1) Install in the reverse order of removal.
Tightening torque:
66 N·m (6.7 kgf-m, 48.7 ft-lb)
2) Adjust the parking brake. JUSTMENT, Parking Brake Assembly (Rear Disc
Brake).>
C: INSPECTION
1) Check the rear wheel bearing play and axle hub
runout before inspecting the disc rotor runout limit.
Bearing.>
2) Secure the disc rotor by tightening the five wheel
nuts.
3) Set a dial gauge 10 mm (0. 39 in) inward from
the disc rotor outer circumference. Rotate the disc
rotor to check runout. If the disc rotor runout ex-
ceeds the limit, replace with a new disc rotor. After
grinding, check disk rotor thickness according to
step 4).

A: INSPECTION
1) Check that the brake fluid level is between “MIN”
and “MAX”. If out of the specified range, refill or
drain fluid. If the fluid level is close to “MIN”, check
the brake pad for wear and refill the fluid.
2) Check the fluid for discoloration. If the fluid color
has changed excessively, drain the fluid and refill
with new fluid.
B: REPLACEMENT
CAUTION:
•Do not let brake fluid come into contact with
the painted surface of the vehicle body. Wash
away with water immediately and wipe off if it is
spilled by accident.
•Avoid mixing brake fluids of different brands
to prevent fluid performance from degrading.
•Be careful not to allow dirt or dust to enter the
reservoir tank.
NOTE:
•During the operation, keep the reservoir tank
filled with brake fluid to eliminate entry of air.
•Operate the brake pedal slowly.
•For convenience and safety, perform work with 2
people.
•The required amount of brake fluid is approxi-
mately 600 m2 (20 US fl oz, 21 Imp fl oz) for entire
brake system.
1) Lift-up the vehicle and set rigid racks at the spec-
ified locations, or keep the vehicle lifted.
2) Remove both the front and rear wheels.
3) Drain brake fluid from the reservoir tank.
4) Refill the reservoir tank with the recommended
brake fluid.
Recommended brake fluid:
Refer to the specification. SPECIFICATION, General Description.>
Perform the same procedure as for bleeding the
brake line, until new brake fluid comes out from vi-
nyl tube. ing.>
NOTE:
Perform the brake fluid replacement starting in or-
der from the farthest wheel cylinder from the mas-
ter cylinder.

C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Use SUBARU genuine grease etc. or equivalent. Do not mix gear oil, grease, etc. with those of different
grades or from other manufacturers.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
•Apply gear oil onto sliding or revolution surfaces before installation.
•Before installing the O-ring or snap ring, apply a sufficient amount of gear oil to avoid damage and defor-
mation.
•Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
•Avoid damaging the mating surface of the case.
