Common Problems with the Toyota Sienna Brake Pad Set
Your Toyota Sienna brake pad set is built to slow down and stop your car even at high speeds. Brake pads basically convert kinetic energy into thermal energy through friction. As you step on the brakes, the pads squeeze together into the brake rotor, generating enough friction and heat to stop or slow down your vehicle. Due to the amount of heat, stress, and friction a brake pad set undergoes through every time, it becomes prone to wear-and-tear. If you notice brake dust accumulating on your vehicle's front or rear wheels, screeching noises when you step on the brakes, or uneven wear on the pads, it's best to perform some troubleshooting. Below are some brake pad set problems encountered by Toyota Sienna owners, and the factors behind them:
Tapered pads
When you notice that your brake pad set is showing a difference in the thickness at one end, it's usually caused by a malfunctioning brake caliper. This will result to a screeching noise when you apply the brakes or uneven pressure when applying the brakes. Check your vehicle's caliper to see if there is excessive clearance between it and the rotor. Tapered pads also need to be replaced immediately.
Uneven pad wear
If you begin to feel brake judders and hears squealing while the brakes are engaged, this could be caused by uneven pad wear. Inspect the brake pad set and brake disc surface for deep grooves. When you find these groves on the pads and disc, you need to replace both parts soon to avoid accidents while driving.
Damaged brake pads
A faulty brake caliper and an improper balance in the vehicle's braking system can cause damage to the brake pads. Excessive heat literally cooks the brake pad set's friction material causing it to break up. Check your brake pad set and determine the source of the excessive heat. Fix the source immediately and change the damaged brake pad set.
Glazed brake pad set
Improper bedding procedures are the common factors behind glazed brake pad sets. Since brake pad sets are designed with porous outer coverings, excessive heat causes the surface to glaze or produce a reflective surface. The pad loses its grip on the rotor, making it slide. When you see that your brake pad set is already glazed, change them with a brand new set immediately.
