Toyota Sienna Maintenance – Change Brake Pads

Are your Toyota Sienna brake pads squeaking or grinding? Replace them today. Here is how to do it.

Before you begin this repair on your own, you will want to make sure you have ample workspace and time. Plus, make sure you have a full complement of automotive tools at your disposal. By taking your time and having the right tools/workspace, this job is fairly straightforward. Rushing, working in a dim/cramped space, or not having the right tools can cause this repair to turn into a nightmare.

The Repair

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:

1. 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.
2. Remove the tires and set aside the lug nuts.
3. Find the brake caliper and remove it by supporting the sliding pin and undoing the bolt.
4. 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.
5. Remove the two anti-squeal springs, the old brake pads, four anti-squeal shims, and the four support plates.
6. After the old parts are removed, put in the new parts starting with the brake pad support plates.
7. Then, place a pad wear gauge plate to each brake pad. Also, replace the anti-squeal shims and support plates. Finally, add an anti-squeal compound to each side of the inner shim.
8. Push the brake caliper back together with either a C-clamp with an old brake pad or a special tool.
9. Once, the caliper is compressed, install the new brake pads with the pad wear indicator facing up.
10. Now, place the caliper back on the rotor and attach the sliding main pin. Use your torque wrench and tighten to 25 foot-pounds.
11. Replace the tires and lower the Sienna back to the ground.
12. 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.
13. 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.

PU Resin For Inks

PU resin is one of the most suitable base materials for ink.
It can provide the ink with good pigment dispersity, adhesive force, and some other performance like heat resistance, adhesion with OPP or PE film and so on.
PU resin of ink can be divided into 3 types because of the ink types, including inside composite ink, surface composite ink and water-based composite ink. But all of the them are suitable for gravure printing rather than other printing methods.
We have different resin which can be suitable for NC or ester. They can show various abilities like boiling water resistance, good adhesion with OPP, low odor and so on.

We can also provide suggestions about product formula.

PU resin, also known as polyurethane resin, is a type of synthetic resin that is widely used in the production of inks. It is a versatile material that offers various benefits for ink formulations.

One of the main advantages of using PU resin in ink is its excellent adhesion properties. It forms a strong bond with different substrates, including paper, cardboard, plastic, and metal, ensuring that the ink adheres well to the surface and resists smudging or rubbing off.

PU resin also provides good gloss and transparency, resulting in vibrant and visually appealing prints. It enhances the color intensity and clarity of the ink, making it suitable for high-quality printing applications.

In addition, PU resin offers excellent resistance to water, chemicals, and abrasion. This makes the ink more durable and long-lasting, ensuring that it remains intact even under harsh conditions.

Furthermore, PU resin can be formulated to have fast drying properties, allowing for faster production speeds in printing processes. It also has good flexibility and elasticity, which helps prevent cracking or flaking of the ink film.

Overall, PU resin is a popular choice for ink formulations due to its excellent adhesion, gloss, transparency, resistance, and drying properties. It is commonly used in various printing applications, including packaging, labels, decals, and graphic arts.
