Front brake pad and rotor replacement can address worn linings, scoring and braking vibration on a 2004–2010 Toyota Sienna equipped with the correct 296 mm front discs. Squealing, grinding, pulling or a pulsing pedal still need diagnosis: a sticking caliper, hub problem or tire fault can cause similar symptoms. No dedicated OBD-II trouble code proves that these mechanical pads or rotors are worn. An ABS warning requires separate diagnosis.
This guide covers replacing both front rotors and all four front pads on the Sienna. The featured kit also has selected Toyota and Lexus applications listed below. Those catalog matches do not make the Sienna procedure universal; use the appropriate vehicle’s service instructions for another model.
Safe lifting, brake inspection and accurate torque control required.
Both front wheels; ordinary corrosion and no hydraulic repairs.
Budget allowance for the axle set, not a live listing price.
Featured front rotor-and-pad kit
A-Premium 296 mm front vented rotors and ceramic brake pads
Part number: APBRPR427 · ASIN: B0B5KYWGNK
The front-left/front-right package contains two rotors and four pads. The seller also lists installation hardware and high-temperature grease. This is a six-main-piece front axle set; it does not include calipers or rear brakes. The rotors have five wheel-bolt holes, and the listing specifies a 26 mm discard thickness. A pad wear indicator is not supplied.
Compare labels, disc diameter, hat offset, pad outline and hardware with the vehicle before installation. Diameter alone cannot establish fitment.
Vehicle compatibility
| Make / model | Years | Engine / configuration | Scope |
|---|---|---|---|
| Toyota Sienna | 2004–2010 | Match engine and drivetrain by VIN; no extra engine restriction is stated in this listing. | 296 mm front brakes; procedure covered below. |
| Lexus ES300 | 2002–2003 | Confirm exact vehicle configuration and original brake dimensions. | Additional catalog application; use Lexus service instructions. |
| Toyota Avalon | 2005–2007 | Confirm exact vehicle configuration and original brake dimensions. | Additional catalog application. |
| Toyota Camry | 2005–2006 | SE/XLE V6 3.0 L or 3.3 L as listed; do not extend to other trims or four-cylinder models. | Restricted catalog application. |
| Toyota Solara | 2004–2008 | Confirm exact vehicle configuration and original brake dimensions. | Additional catalog application. |
Confirm the exact year, model, trim, engine and drivetrain in the fitment selector and compare original brake equipment. The table does not claim every Toyota shares this kit. Previous brake conversions also require a physical parts comparison.
Diagnose before ordering
- Squealing: inspect pad thickness, wear indicators, glazing and loose shims. Noise alone does not prove a rotor is defective.
- Grinding: stop driving and inspect for worn-through pads, debris or damage. Continuing can ruin additional parts.
- Pulsation: measure rotor thickness variation and runout; inspect the hub face and bearing. A dirty hub can make a new disc wobble.
- Pulling or heat: compare inner and outer pad wear, pin movement and piston behavior. A sticking caliper or restricted hose is a different repair.
- Vibration without braking: also investigate wheels, tires and suspension.
Inspect all four front pads. An outer pad visible through the wheel can look healthy while the inner pad is nearly gone. Measure the discs at several positions clear of their wear lips. Keep left/right notes so an uneven wear pattern is not lost when the old parts are discarded.

DIY versus professional cost
| Expense | Planning estimate | Assumption |
|---|---|---|
| Front rotor/pad set | $100–$220 | Shopping allowance, not a current listing price. |
| Consumables / minor hardware | $20–$60 | No caliper, hose or hub repairs included. |
| Tools already owned | $0 additional | Only if serviceable and suitable. |
| Tools from scratch | $250–$650+ | Reusable lifting, torque and inspection equipment. |
| DIY total, existing tools | $120–$280 | Both front wheels; tax and unexpected repairs excluded. |
| Shop labor | $180–$400 | Assumed 1.5–2.5 hours at $120–$160/hour. |
| Shop total | $350–$750 | Allowance for shop-supplied parts, labor and consumables. |
These are planning estimates, not a flat-rate guide or guaranteed quote. Ask whether a shop includes both rotors, four pads, slide service and hub inspection. Buying every tool for one repair can outweigh the labor saving.
Sienna front-brake specifications
| Item | Specification | Application |
|---|---|---|
| Bracket to knuckle | 107 N·m (79 ft-lb) | Sienna front caliper bracket bolts. |
| Caliper / slide-pin bolts | 34 N·m (25 ft-lb) | Smaller caliper-body bolts. |
| Wheel nuts | 103 N·m (76 ft-lb) | Original wheel fastening arrangement; tighten evenly. |
| Rotor runout | Maximum 0.05 mm (0.0020 in.) | Measure 10 mm inward from the outside edge. |
| Featured rotor discard thickness | 26 mm | Check the actual disc’s marking; replace at or below its limit. |
Identify each fastener correctly. Use sound threads and the specified assembly condition; do not add oil or anti-seize to wheel studs or brake bolt threads to compensate for corrosion. If previous repairs changed the caliper or hardware, confirm those components’ requirements first.
Step-by-step replacement overview
1. Prepare and support the Sienna
Park, shut off the engine, secure the key and allow the brakes to cool. Apply the parking brake and chock a rear tire ahead and behind. Loosen wheel nuts slightly before lifting. Use the designated floor-jack point and approved stand locations from the Sienna lifting instructions, with enough capacity and stable saddle contact. Verify stability before removing the wheel. Complete one side before dismantling the other so it remains a reference.
2. Inspect and plan the fluid level
Check for leaks, torn piston boots, damaged hoses and uneven pad wear. Photograph the pad, shim and wear-indicator arrangement. Protect nearby paint and monitor the reservoir during piston retraction. Do not automatically top up fluid just because worn pads have allowed the piston to move outward; the level will rise when it is pushed back.
3. Remove and support the caliper
Remove the slide-pin bolts using the correctly fitting socket or wrench. Counterhold a turning pin without damaging its boot. Lift the caliper away and hang it from a strong point with the hose attached, untwisted and slack. Do not press the brake pedal with the caliper removed. Take out the pads and organize their hardware.
4. Remove the bracket and rotor
Undo the bracket-to-knuckle bolts and remove the bracket, then slide the rotor off. If seized, use the vehicle-specific removal method; uncontrolled hammering can damage adjacent parts. After safely removing dust, clean the hub mounting face without gouging it or removing base metal. Check the hub and bearing for damage or abnormal play before covering them with a new disc.
5. Fit and measure the new disc
Follow the rotor maker’s directions for shipping-preservative removal. Keep the friction and hub mating surfaces free of oil and grease. Seat the disc fully and secure it using the service-manual wheel-nut arrangement. With a rigidly mounted indicator, measure runout 10 mm in from the outer edge. Toyota specifies a maximum of 0.05 mm. If excessive, check hub cleanliness and bearing play, re-index the disc and remeasure. Persistent runout needs diagnosis; do not simply tighten harder.
6. Service the slides and fit pads
Inspect pins, boots and supports. Keep each pin in its original position, including the lower pin’s bushing arrangement. Replace damaged pieces; pins must move smoothly. Apply the specified lithium-soap-base glycol grease sparingly to the sliding and rubber-contact areas. Refit the bracket and torque its bolts to 107 N·m (79 ft-lb). Install the correct supports, shims and new pads without forcing them. Toyota’s Sienna instructions place the wear indicator upward. Use pad/shim grease only where the applicable instructions allow it, never on the lining.
7. Retract and reinstall the caliper
Seat the spreader with an old pad distributing its load, and compress the piston slowly, straight inward. Monitor the reservoir; remove excess with clean, dedicated brake-fluid equipment if needed to prevent overflow. Stop for a piston that sticks or a boot that folds or tears. Position the caliper over the pads without trapping hardware or twisting the hose. Torque slide-pin bolts to 34 N·m (25 ft-lb). Check for incorrect clip contact, then repeat on the opposite front wheel.
8. Finish stationary checks
Refit the wheels, hand-start their nuts and lower the vehicle safely. Tighten in a star pattern to 103 N·m (76 ft-lb). Before moving, pump the brake pedal with the engine off until firm. Inspect for leaks, check that reservoir fluid is between its marks and secure the cap. Check assisted pedal operation after starting. Stop for a soft, sinking or abnormal pedal; more pumping is not a repair for a hydraulic fault.
9. Test and bed the brakes
After all stationary checks pass, test at walking speed in a clear, safe area. Stop for pulling, unusual noise, drag, warning lights or poor pedal response. Follow the kit’s supplied bedding instructions and avoid demanding use until normal operation is established. Do not improvise a high-speed series of stops on public roads.

Common mistakes
- Ordering by diameter alone or extending Camry V6 fitment to a four-cylinder model.
- Replacing only one side or ignoring a seized slide that caused uneven wear.
- Leaving rust between the hub and rotor, or skipping runout measurement.
- Mixing bracket and slide-pin torque values or using an impact for final tightening.
- Putting petroleum grease on rubber or contaminating the friction surfaces.
- Reusing missing or damaged indicators and shims because the kit does not supply them.
- Moving the vehicle before the pedal is firm and the wheels are torqued.
Frequently asked questions
Does this fit every 2005–2006 Camry?
No. The listing restricts that application to the SE/XLE V6 configurations shown in the table. Shared model names do not prove identical brakes.
Will new pads fix an ABS warning?
Not by themselves. Diagnose the ABS fault separately; ordinary friction wear is not proof of a failed sensor or control module.
Do I need to bleed the brakes?
Routine pad-and-rotor work can leave the hydraulic circuit closed. Opening a hose or bleeder, finding a leak or letting the reservoir empty changes the job and requires appropriate hydraulic service. A soft pedal blocks road use.
Can I skip the measuring tools?
A visual inspection cannot establish disc runout or thickness. Arrange a brake shop’s measurements if suitable instruments are unavailable, especially when diagnosing pulsation.
Why might new brakes still drag?
Check pad movement in the supports, slides, piston and hose. Stop if a wheel overheats. Buying another kit without finding the cause repeats the expense.
