The Suburban has been in the GM family for many agedness as a blimp SUV. Although the vehicle has been terminated many generations and redesigns, replacing the brakes has remained relatively unchanged. There are slight differences between the weight ratings of the vehicle (1/2 ton, 3/4 ton, and dual rear rotate models) nevertheless the solution is resembling. Replacing the rotors normally indicates a headache with the rotor. Scoring or Exorbitant runout (warping of the rotor which results in vibrations during braking) are accepted reasons for replacing rotors.
Instructions
Replace Brake Rotors on a Suburban
1. Compass the Suburban safely and securely onto a vehivle lift. Before lifting, Proceeds the hood hook and remove the masterly cylinder subsume. Remove 2/3 of the brake fluid from the master cylinder by sucking it gone with a brake fluid siphon. Interchange the insert.
2. Lift the Suburban to a comfortable heighth to functioning on the brakes (waist exact). Remove the hub caps and then remove the lug nuts using the pressure gun and a socket. Remove the wheels.
3. Remove the front spin hub extent provided relevant (dual rear circle models). Comprehend the screwdriver or pry bar concluded the caliper Harbour and into one of the brake rotor vents to prevent it from Stirring. Assemble a objective with a tire crayon on one of the lug studs and further on the shove hub time to set up the consanguinity between the the extent and its position on the hub. When it comes hour to moderate the hub time, it is strongly suggested to place it on the hub in the identical position in which it was removed. Marking the hub and the stud Testament confirm you are replacing it by reason of fashion. Remove the rotor. If necessary, spray penetrating oil into the two threaded holes in the front hub face of the rotor. Insert the two 10x1.5 millimeter bolts into the holes and then tighten them alternately with the ratchet and a socket to draw the rotor from the hub. Remove the bolts to reuse on the other rotor if desired.
Involve the substantial screwdriver or pry bar into the front plain Harbour of the caliper and pry the borderline of the rotor against the caliper piston. This Testament compress the piston of the caliper Sufficiently to remove it from the knuckle. Pry the rotor through slowly and as far as it will allow you to. The replacement rotor will be thicker than the existing one so more room will be necessary when you're ready to reinstall the caliper onto the new rotor.
5. Remove the caliper assembly by removing the two caliper assembly bolts with the impact gun and socket. A swivel may be required to properly seat the socket onto the caliper assembly bolts. Remove the caliper assembly and secure it with mechanic's wire to a front-end component so it does not hang by the hydraulic caliper hose.
6. Remove the extent bolts with the gun and a socket and then remove the room. Tap it with a rubber mallet whether needed to cleft it complimentary from the hub. Whether a revolve hub space is not demonstrate, skip this action and proceed To pace 4.4.
7. Clean the surface of the hub using an angled die grinder and reconditioning disc. Be sure to wear safety glasses before attempting this. Clean the face of the hub and the edges (that the replacement rotors will contact) of the hub so that they're free of burrs, rust, and corrosion build-up with the die grinder.
8. Clean off the oily residue on the replacement rotors by spraying on brake clean solvent. Install the new rotor onto the hub. If applicable, replace the wheel hub extension and bolts.
9. Replace the caliper assembly and bolts.
10. Replace the wheel and lug nuts. Be sure to torque the lug nuts per proper torque specifications of the particular Suburban year and model you're working on. Replace the hub cap.
11. Repeat steps 3 through 10 for the other rotor.
12. Lower the Suburban to the ground and pump the foot brake pedal to seat the pads against the new rotors. Check and add brake fluid to the master cylinder.
