The Toyota Sienna needs regular maintenance like any other vehicle and this maintenance includes the brakes. If your brakes are squeaking or grinding, it is probably time to change them. Here’s how.
Once you have everything ready to go, remember safety first. Make sure you park your Toyota Sienna on a level piece of ground and you use the parking brakes. Lastly, if you need to order new brake pads, you can do that here.
In order to do this repair, you will need a floor jack or hydraulic pump, jack stands, an assortment of sockets and a torque wrench. Then, follow these steps:
- Loosen the lug nuts and lift the van into the air with the floor jack or hydraulic pump. Make sure you support it with jack stands.
- Remove the tires and set aside the lug nuts.
- Find the brake caliper and remove it by supporting the sliding pin and undoing the bolt.
- Don’t drop the brake caliper and instead support it with either a mechanic wire, shirt hanger or some other way. If you allow it to dangle, it might snap the brake line which would cause a lot bigger problem.
- Remove the two anti-squeal springs, the old brake pads, four anti-squeal shims and the four support plates.
- After the old parts are removed, put in the new parts starting with the brake pad support plates.
- Then, place a pad wear gauge plate to each brake pad. Also, replace the anti-squeal shims and support plates. Finally, add anti-squeal compound to each side of the inner shim.
- Push the brake caliper back together with either a C-clamp with an old brake pad or a special tool.
- Once, the caliper is compressed, install the new brake pads with the pad wear indicator facing up.
- Now, place the caliper back on the rotor and attach the sliding main pin. Use your torque wrench and tighten to 25 foot-pounds.
- Replace the tires and lower the Sienna back to the ground.
- Next, climb into the driver’s seat and apply the brakes. They will feel soft and you will need to pump them a few times. Your brakes should return to normal.
- Check the brake fluid before completing this repair. Quite often, you will lose some or you may have let some out during the process.
Congrats! You just changed the brakes in your Toyota Sienna.
