Question about 2002 Toyota MR2 Spyder

1 Answer

Rear brake pad replacement, can't get caliper to compress down.

I have gotten the pads out no problem and can get the new ones in just fine, but I can't seem to figure out how to get the caliper to compress down so I can then slide the assembly back over the rotor. Someone told me they crank down, but I don't see how to do that. Greatly appreciate the help as I can't stand taking this to the shop for something that should be so easy.

    Hi Mackinbeats,



    I will give that a try, but typically speaking the large channel locks that I have used for the front and for all my other cars tend to get the job done. I have a hard time believing that they are that tough to move compared to the front ones, but thanks for the input and I'll let you know how it works out.

    Hi Mackinbeats,



    Unfortunately it has been a crazy week with little time to myself. I probably am two weeks away from getting back to the Spyder. The good news is the brakes on it now are just fine, so I am not in an emergency fix it mode just yet. I'll definitely post how it works out.



    Thanks,

    Rick

Steps to replacing rear brake pads


A special tool is required to compress the caliper piston on the rear brakes-don't use a C-clamp on the piston.
Raise the vehicle and remove the tire. The rear calipers have only one guide pin. Remove this pin and raise the caliper. Remove the old brake pads. Using the special tool compress the caliper piston-the piston will have one or two slots on it. These slots must in the correct position to remount the caliper. Install the new brake pads and slide the caliper back over the rotor and replace the guide pin. If the caliper doesn't slide over the rotor you'll need to reset the slots on the piston. Replace the tires and you're ready to go.

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.

How to replace rear brake pads


Jack up car, remove wheel. There are two bolts that hold the caliper on. Remove these. Caliper comes off, take old pads out. There is a special tool to compress the piston back into the caliper (do not use a C Clamp on the rears.) Put new pads back on, re-install the caliper, and put the wheel back on. Pump the brake pedal until it is firm. Done.

I am replacing the rear pads and cannot get the caliper to compress using a c-clamp. Is there something special I need to do or know on my montego 05 car to get the caliper to compress? Sincerely Desperate...


One, take your brake fluid reservoir cap off.
Two, use a thin piece of wood to help you compress the piston on the caliper....do it slow. This way, you don't create a lot of pressure to the reservoir and it won't overflow.
Three, these are the steps to removing and replacing the pads for the rear. It does mention a special tool....but you can use a c-clamp for the same purpose:

Rear To Remove:
  1. Check the brake fluid level in the brake master cylinder reservoir.
  2. If required, remove the fluid until the brake master cylinder reservoir is half full. CAUTION
    Care must be taken when servicing rear brake components without disconnecting the parking brake cable from the brake caliper lever.
  3. Remove the disc brake caliper. Support the caliper with mechanic's wire. CAUTION
    When the brake pads are separated from the brake caliper, new brake pads must be installed. The brake pads are one-time use only.
  4. Remove and discard the brake pads and spring clips from the brake caliper anchor plate. NOTE: Do not remove the anchor plate guide pins. The guide pins are press fit to the brake caliper anchor plate. If the guide pins are damaged a new anchor plate must be installed.
  5. Inspect the brake caliper anchor plate assembly.
  6. Check the guide pins and boots for binding or damage.
  7. Install a new brake caliper anchor plate if it is worn or damaged.
To Install:
NOTE: The left caliper piston turns clockwise and the right caliper piston turns counterclockwise.
  1. Using the special tool, turn and compress the brake caliper piston into the cylinder.
  2. Clean the residual adhesive from the brake caliper fingers and pistons using the specified brake parts cleaner. CAUTION
    Do not allow grease, oil, brake fluid or other contaminants to contact the brake pad or caliper mating surface. Do not install contaminated pads.
    NOTE: Install all the new hardware supplied with brake pad kit.
  3. Install the new spring clips and brake pads.
  4. Position the brake caliper and install the 2 bolts. Tighten caliper bolts to 23 ft-lbs (31 Nm).
  5. If necessary, fill the brake master cylinder reservoir with clean brake fluid.
  6. With the engine running, apply pressure on the brake pedal to seat the brake pads.
  7. Test the brakes for normal operation.
