Chrysler Sebring, Stratus sedan, Sebring Convertible. Manual - part 290

Hub runout should not exceed 0.05 mm (0.0019

inch). If runout exceeds this specification, the hub
must be replaced. Refer to SUSPENSION.

If the hub runout does not exceed this specifica-

tion, install the rotor back on the hub, aligning the
chalk marks on the rotor with a wheel mounting
stud, two studs apart from the original stud (Fig. 59).
Tighten nuts in the proper sequence and torque to
specifications.

Recheck brake rotor runout to see if the runout is

now within specifications.

If runout is not within specifications, reface or

replace the brake rotor. For information on brake
rotor machining, (Refer to 5 - BRAKES/HYDRAU-
LIC/MECHANICAL/ROTORS - STANDARD PROCE-
DURE).

STANDARD PROCEDURE - BRAKE ROTOR
MACHINING

NOTE: Refacing the rotor is not required each time
the brake pads are replaced, only when the need is
foreseen.

Any servicing of the rotor requires extreme care to

maintain the rotor within service tolerances to
ensure proper brake action.

If the rotor surface is deeply scored or warped, or

there is a complaint of brake roughness or brake
pedal pulsation, the rotor should be refaced using a
hub-mounted

on-car

brake

lathe

(Fig.

60),

replaced.

The use of a hub-mounted on-car brake lathe is

highly recommended to eliminate the possibility of
excessive runout. It trues the brake rotor to the vehi-
cle’s hub and bearing.

ROTOR (Continued)

NOTE: All rotors have markings for minimum allow-
able thickness cast on an un-machined surface of
the rotor (Fig. 61).

Minimum allowable thickness is the minimum

thickness which the brake rotor machined surface
may be cut to.

CAUTION: Do not machine the rotor if it will cause
the rotor to fall below minimum thickness.

Before installation, verify the brake rotor face and

the hub adapters are free of any chips, rust, or con-
tamination.

When mounting and using the brake lathe, strict

attention to the brake lathe manufacturer’s operating
instructions is required.

Machine both sides of the brake rotor at the same

time. Cutting both sides at the same time minimizes
the possibility of a tapered or uneven cut.

SPECIFICATIONS AND LIMITS

When refacing a rotor, the required TIR (Total

Indicator Reading) and thickness variation limits
MUST BE MAINTAINED. Extreme care in the oper-
ation of rotor turning equipment is required.

REMOVAL

REMOVAL - FRONT ROTOR

(1) Raise the vehicle. (Refer to LUBRICATION &

MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)

(2) Remove the front tire and wheel assembly.
(3) Slide the caliper outward in an effort to retract

the caliper piston into its bore.

(4) Remove the two bolts securing disc brake cali-

per adapter to the steering knuckle (Fig. 62).

(5) Remove the disc brake caliper and adapter

from the knuckle as an assembly. Hang the assembly
out of the way using wire or a bungee cord. Use care
not to overextend the brake hose when doing this.

(6) Remove the clips retaining the brake rotor to

the wheel studs.

(7) Remove the brake rotor.

REMOVAL - REAR ROTOR

(1) Raise vehicle. (Refer to LUBRICATION &

MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)

(2) Remove rear tire and wheel.
(3) Remove the caliper and shoes from adapter and

hang out of way. (Refer to 5 - BRAKES/HYDRAULIC/
MECHANICAL/BRAKE PADS/SHOES - REMOVAL)

(4) Remove any clips on the wheel mounting studs.
(5) Remove rotor from hub (Fig. 63).

(1) Install the brake rotor over the studs on the

hub.

(2) Install the disc brake caliper and adapter

assembly over the brake rotor.

(3) Install the mounting bolts securing the caliper

adapter to the steering knuckle (Fig. 62). Tighten the
bolts to a torque of 80 N·m (60 ft. lbs.).

(4) Install the tire and wheel assembly. Tighten

the wheel mounting nuts to a torque of 135 N·m (100
ft. lbs.).

(5) Lower the vehicle.
(6) Pump the brake pedal several times before

moving the vehicle to set the shoes to the brake
rotor.

SUPPORT PLATE

REMOVAL

NOTE: Before proceeding, (Refer to 5 - BRAKES -
WARNING) (Refer to 5 - BRAKES - CAUTION).

NOTE: Make sure parking brake is in “released”
position before raising vehicle.

(1) Depress brake pedal past its first inch of travel

and hold it in this position using a brake pedal
depressor (holding) tool. This is done to isolate mas-
ter cylinder from brake hydraulic system disallowing
brake fluid to completely drain out of brake fluid res-
ervoir once brake flex hose is disconnected.

(2) Raise vehicle. (Refer to LUBRICATION &

MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)

(3) Remove tire and wheel assembly.
(4) Unthread flex hose tube nut at wheel cylinder

and remove hose (Fig. 64). Cap end of hose.

(5) Remove flex hose routing bracket screw and

move hose out of way (Fig. 64).

(6) Remove brake drum. (Refer to 5 - BRAKES/HY-

DRAULIC/MECHANICAL/DRUM - REMOVAL)

bearing assembly, and brake shoes from support
plate. (Refer to 5 - BRAKES/HYDRAULIC/MECHAN-
ICAL/BRAKE PADS/SHOES - REMOVAL)

(8) Disengage and remove parking brake cable

from support plate. This can be easily accomplished
by placing a 13 mm box wrench over cable housing
retainer (Fig. 65), compressing retainer fingers, then
pulling cable out rear of support plate.

(9) Remove wheel cylinder mounting bolts (Fig.

66).

(10) Remove wheel cylinder and seal from support

plate.

(11) Remove 4 bolts securing support plate to

knuckle.

(2) Install four support plate mounting bolts.

Tighten mounting bolts to 61 N·m (45 ft. lbs.) torque.

(3) Install seal on mounting surface of wheel cylin-

der.

(4) Install wheel cylinder on support plate (Fig.

66). Install and tighten mounting bolts to 13 N·m
(115 in. lbs.) torque.

(5) Insert parking brake cable into support plate.

Push cable housing into hole until retainer fingers
lock into place.

(6) Lubricate six shoe contact areas on support

plate and anchor using Mopar

t Brake Lubricant or

equivalent.

(7) Install brake shoes, hub and bearing, and hub

and bearing dust cap. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/BRAKE

PADS/SHOES

plate (Fig. 64). Tighten routing bracket screw to 13
N·m (115 in. lbs.) torque.

(11) Thread flex hose tube nut into wheel cylinder

port (Fig. 64). Tighten tube nut to 17 N·m (145 in.
lbs.) torque.

(12) Install tire and wheel assembly. Tighten

wheel mounting nuts to 135 N·m (100 ft. lbs.) torque.
