How to replace the rear drum brakes on a first generation Toyota Tacoma 4wd, this particular truck is a 2001 model. This truck will be getting new shoes, spring kit, and drums. In order to produce this video, Bosch has been kind enough to provide me with the parts required for this replacement. A similar procedure may also apply to the Toyota Tundra and Toyota 4Runner. #toyota #toyotatacoma #toyota4runner

-clean rags

Procedure:
Safely elevating the rear of the trunk, one side can be done at a time, then remove the Hold the pin on the rear, then push the spring retainer down and rotate 90 degrees to disconnect and then remove.
Pull the parking brake mechanic back by hand, then unclip the cable. Remove the cable on the opposite side. Pull the adjuster lever back, then retract the adjuster screw so the pads are compressed.
While this is in place, you can remove the c-clip off the adjuster lever. Behind that is a pinched c-clip, so while this is in place, it’s held so it’s a bit easer to expand this clip and remove. Now pull down the bottom of the pads to disconnect them off the pivot location. Pull the pads from the wheel cylinder and pivot location will help relieve some tension on the springs, making the removal a bit easier.
Disconnect the lower spring and the spring on the top from the brake shoes. Careful around the wheel cylinder boots, do not damage them. And now remove the brake shoes completely. You’ll need to maneuver shoes around the parking brake lever.
Using brake cleaner wash away brake dust into a drain pad and the wipe clean with a rag. It’s important to match up the old and new pads to ensure they are the same. There is a difference between the primary and secondary shoes, ensure you have them in the correct position.
I will be reusing the parking brake assembly as it’s still in good condition along with the automatic adjusters. Clean the components using brake cleaner to remove any dust and then assemble the components. First the lever for the parking brake. New c-clips will be supplied with the new spring kit. Install the c-clip and using pliers, squeeze over the end so the clips are locked into place. Install the adjuster lever. Then install the c clips, do not loose the old ones as new clips may not be supplied in the spring kit.
Check the function of the adjuster screw assembly. This should move freely. Clean as needed and apply new grease or if it’s too far gone, then replace. I do have a video for the clean and lubrication procedure. Install it into place, there will be a tab that clips into the adjuster lever. Flipping the shoe over, there is a spring which connects to the adjuster lever and shoe slot.
You’ll also need to install the return spring which clips in on the backside. Install the new hold down pin with retaining spring. Install the opposite shoe. Again installing the hold down pin with retaining spring. Pull the return spring into place using pliers.
The lower spring at the lower pivot point can be installed, this clips in from the backside. Install the cable for the parking brake, first clipping on the loop side. Pull back the lever and then clip the cable into place.
This truck will also be getting new drums. In this case the new drums have a packaging oil which does need to be cleaned before they’re installed, brake cleaner or brake wipes can be used for this.
Adjust the drum brakes before installing the wheel. In order to do this, you’ll need to expand the shoes by the adjuster screw, either from the front or rear of the drum brake assembly. You can also operate the parking brake bell crank by hand, but this only moves the adjuster one notch at a time so it’s certainly a slower route.
When the shoes are close into position, install the drum brake and then press the brake pedal to center the shoes. Revisit the adjuster again, there should be mild drag when installing and removing the drum. Install the wheel, the torque specification for the wheel is 85ft lbs or 115nm. Then move onto the opposite side.
