Firebird V8-350 5.7L VIN P SFI (1996)
may come out with force resulting in serious injury.
NOTE: Use clean cloths to pad interior of caliper housing during piston removal. Use just enough air to ease the piston out of the bore. If the
piston is blown out, even with the padding provided, it may be damaged.
Removing Rear Brake Caliper Piston
6. Piston (19) by directing dry, filtered compressed air into brake hose port of rear brake caliper (14). Inspect Piston (19) for scoring, nicks,
corrosion and wear. Replace piston (19) if necessary.
NOTE: Do not use a metal tool to remove the piston seal from the rear brake caliper bore. Using a metal tool may damage the caliper bore or seal
groove.
7. Caliper piston seal (18). Use small wood or plastic tool.
8. Bleeder valve cap (7) and bleeder valve (6). Discard bleeder valve cap (7).
9. Parking brake lever pivot pin cap (1), spray clip (2), actuator lever return spring (4) and parking brake actuator lever (5) from parking brake lever
pivot pin (3). Discard spray clip (2). Inspect Contact points on parking brake actuator lever (5) and parking brake lever pivot pin (3) for wear and
corrosion. Replace if necessary.
10. Parking brake lever pivot pin (3) and pivot pin nut (12), if worn.
11. Adjuster screw (11) from rear brake caliper (14). Discard if damaged or worn. Inspect Caliper mounting plate (17) for wear and damage. Replace
if necessary. Refer to Rear Brake Caliper Mounting Replacement. Clean Pad contact area on mounting plate (17).
12. Two guide pins (15) and guide pin boots (16) from mounting plate (17).Clean All parts not included in repair kit in denatured alcohol. Use dry,
filtered compressed air to dry parts. Blow out all passages in rear brake caliper (14) and bleeder valve (6). Inspect Rear brake caliper bore for
scoring and corrosion. Replace rear brake caliper (14) if badly scored or corroder1 around seal area.
ASSEMBLE
1. Lubricate new caliper piston seal (18) and caliper housing bore seal groove with silicone grease or clean brake fluid.
2. New caliper piston seal (18) into caliper housing seal groove. Make sure caliper piston seal (18) is not twisted.
3. Lubricate bore of rear brake caliper (14) and piston (19) with clean brake fluid.
4. Piston (19) into bore of rear brake caliper (14). Push down by hand to bottom of bore. Inspect Actuating collar (24) and clamp rod (28) for
corrosion and excessive wear on working faces. If corrosion or excessive wear is present, replace actuating collar.
5. Pushrod (22), new brake caliper piston boot (20), actuating collar boot (25) and new actuating collar boot retainers (21 and 31) to actuating collar
(24). Lightly coat actuating collar (24) with liquid lubricant provided in repair kit. Do not use any other fluid or grease. Install preload spring (23)
into new actuating collar boot retainer (21). Install new brake caliper piston boot (20), actuating collar boots (20) into new actuating collar boot
retainers (21 and 31). Install pushrod (22) to new actuating collar boot retainer (21). Clamp new actuating collar boot retainers (21 and 31) firmly
against actuating collar (24). Bend tabs on new actuating collar boot retainer (21) to hold actuating collar assembly together.
6. Clamp rod (28) to actuating collar (24) and actuating collar boot (25). Lightly coat clamp rod (28) with liquid lubricant provided in repair kit.
Slide clamp rod (28) through holes in actuating collar boot (25) and actuating collar (24). Actuating collar boot (25) must be against reaction plate
on clamp rod (28).
7. New bushing (27) to clamp rod (28). Lubricate outside of bushing (27) wit provided lubricant.
8. Clamp rod (28) with assembled parts into connecting hole in piston (19). Lubricate grooved bead of actuating collar boot (20) and boot groove in
caliper housing (14) with provided lubricant. Use remaining liquid lubricant to coat actuating collar (24), especially around center hole. Push
clamp rod (28) firmly to bottom of connecting hole in piston (19). Pull on actuating collar (24) and seat actuating collar boot (20) into boot groove
in rear brake caliper (14). Make sure that pushrod (22) enters hole in rear brake caliper (14).
9. Two collar return springs (26) to actuating collar boot retainer (31). Actuating collar boot retainer (31) must enter collar return springs (26) at end
of second spring coil.
10. New bleeder valve cap (7) and bleeder valve (6) into rear brake caliper (14). Tighten Brake caliper bleeder valve (6) to 11 Nm (97 inch lbs.).
11. Parking brake lever pivot pin (3) and new pivot pin nut (12) to rear brake caliper (14), if removed. Tighten Parking brake pivot pin nut (12) to 22
Nm (16 ft. lbs.).
12. Lubricate parking brake actuator lever (5) and parking brake lever pivot pin (3) with grease provided in repair kit.
