How To Assemble Rear Drum Brakes On Chevy Trucks?

Assembling your Chevy truck’s rear drum brake isn’t everyone’s cup of tea. It’s not a lie that the job is quite labor-intensive and time-consuming. Not everyone has the time to spare. 

We’ve heard you and gone ahead to make the assembly feel like a breeze to you. Keep your eyes on the steps below to get the job done in no time.

Step 1: Start With The Backing Plate

It’s a wise choice to start with the backing plate which is a large circular metal plate that functions as the solid foundation of the drum brake. 

It’s typically made of steel and has the wheel cylinders and the infamous brake shoes attached to them. The backing plate is called the foundation for a reason. 

If the foundation is not built properly, then the rest of the assembly would just eventually tumble over no matter how strongly it is prepared.

Step 2: Install The First Brake Shoe And Mount The Wheel Cylinder

Hold the wheel cylinder in the right way. Carefully mount it using two bolts. Now start with the primary brake shoe as it is quite a hassle to install so it’s better to get those parts in line first. 

Then hook in the parking brake arm. Now bring out the self-adjuster arm and plug it into the primary brake shoe. Also, take the spring assembly and attach it to the brake shoe. 

Insert the piston onto the wheel cylinder and try to get the spring onto the pushrod hook to create a little bit of tension on the spring.

Step 3: Install The Secondary Shoe And Tighten The Brake Shoes

Now Gently grab the equalizer bar and hook it up with the primary and the secondary brake shoes. Once it’s connected to both ends of the brake shoes, it’s time to get the equalizer lined up with the parking brake arm.

Following the same method as with the primary shoe, get the pushrod and tension spring installed in the secondary shoe without going through any unnecessary headaches. 

If the assembly had been done properly so far, then the secondary shoe wouldn’t jump apart after light installation.

Although the secondary shoe had just been installed lightly, it’s now time to bring in the self-adjuster spring and connect it to both ends of the shoe. Take care as it’s side specific. 

Now, finally, attach the retaining spring to the secondary shoe and connect the self-adjuster to hold the arms in place.

And there you have it, the drum brake of your Chevy should be assembled correctly by now.
