Question about 2003 Chevrolet Blazer

1 Answer

I have a 2003 Chevy Blazer with rear disc brakes. I attempted to change the pads today and found that the bolts were 12mm that were holding the calipers in place. I used my 12mm socked and removed the top bolt. When I went underneath, I found that the spring was too close to the bottom bold to fit my wrench in place. Is there a simple solution to this (like go get a 12mm box / crescent wrench)? Or does the spring need to be removed to access the caliper?

I would assume,you would have a complete
selection of Metric Tools, if you plan on working
on any vehicle from 1980 on

You need open/box combo wrenches

Replace rear brake pads


Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
rear_brake_pads.jpg Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
rear_brake_pads_2.jpg To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
rear_brake_pads_3.jpg After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
rear_brake_pads_4.jpg With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
rear_brake_rotor.jpg Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
rear_brake_rotor_2.jpg Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
rear_brakes_7.jpg Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
rear_brake_rotor_3.jpg After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
rear_brake_rotor_4.jpg Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

Are there any special tools needed to change the brakes on a 2006 toyota sienna? Standard two bolts that hold it on?


You will probably not need anything other than a metric socket wrench set.

Many Toyota models have disc brake calipers that will flip up or down when you remove one of the two bolts that hold the calipers on. I am not sure of the setup on the Sienna.

When you remove either the upper or lower bolt and move the caliper, you can then remove the old pads. Also, you will need to push the piston(s) back into their cylinders to give you enough space to install the new pads. A large C clamp will usually suffice to push in the pistons.

I assume that you are talking about the front (disc) brakes. Some autos still have drum brakes on the rear, and those are a different story. They require several specialty tools to remove and replace the shoes.

I need to repalce the rear brake pads. I have 4 wheel discs and cannot figure out how to get the caliper off to replace the pads.


Look at the back side of the calipers you will see 2- 12mm bolts that hold the caliper on to the brake pad bracket just unbolt and replace pads. Make sure you have a C clap handy to compress the caliper pisiton back into the caliper.

I have never worked on one as I live in australia and I have not seen one here at all but I would imagine they are a similar setup to most modern vehicles.
Remove the wheel, the disc caliper should be in your view now so have a look at both ends of the caliper on the back to see if it has 2 bolts holding the caliper to the mounting plate, you may only need to remove 1 bolt and swing the caliper away from the rotor, if not just remove the 2 bolts and remove the whole caliper from the rotor.
To compress the caliper piston back into the caliper just use a "G" clamp and 1 of the worn out pad backing plates across the front of the piston and use the "G" clamp to compress the piston as you will not be able to get the caliper back over the rotor with the new pads in place.
You will have to replace the rotors if they have been damaged by the worn out brake pads.
Hope this helps you with your problem
