Toyota Sienna Disc Brake Caliper Kit in US

When a caliper on the Toyota Sienna seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your Sienna keeps the brake pad in continuous contact with the rotor, wearing the pad unevenly and scoring the rotor surface. By the time the caliper on the Toyota Sienna is identified as the fault, the pads are typically worn asymmetrically and the rotor is damaged. A caliper kit from GeoBrakes addresses every compromised component on your Toyota Sienna together.

What Is Included in the Toyota Sienna Disc Brake Caliper Kit

The kit for your Toyota Sienna includes the disc brake caliper at the correct left or right hand specification for the Sienna, either new OEM-spec or quality remanufactured to the Toyota Sienna piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the Sienna caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Toyota Sienna, brake lubricant for correct pin and shim installation on your Sienna, and copper washers or banjo bolt seals for the brake hose connection where required by the Toyota Sienna application.

When a Caliper Kit Is the Correct Service Choice for the Toyota Sienna

A caliper kit is the right call for the Toyota Sienna in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your Sienna are already compromised. During a high-mileage Sienna overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Toyota Sienna are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the Sienna brake pad renders the friction material permanently ineffective on your Toyota Sienna.

New vs. Remanufactured Caliper for the Toyota Sienna

New OEM-specification calipers for the Toyota Sienna are manufactured from fresh materials with no prior service history, the strongest choice for Sienna vehicles in high-corrosion environments. Remanufactured calipers use original Toyota Sienna housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most Sienna replacement applications.

Signs the Caliper Kit on Your Toyota Sienna Is Due

• Toyota Sienna pulling to one side during braking, one caliper applying more force than the other
• One brake pad on your Sienna worn significantly more than its pair on the same axle
• Brake drag on the Toyota Sienna with a wheel that runs hot after normal driving
• Soft or sinking Sienna brake pedal caused by a caliper piston seal leak
• Brake fluid visible around the Toyota Sienna caliper piston boot
• Persistent metallic dragging noise from one Sienna corner not explained by worn pads

Why GeoBrakes for the Toyota Sienna Caliper Kit

Calipers for the Toyota Sienna are the most position-specific brake component in the catalogue. Left and right calipers for the Sienna are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Toyota Sienna exact year, axle position, and left or right side before purchase.

Frequently Asked Questions - Toyota Sienna Disc Brake Caliper Kits

Should I replace both calipers on my Toyota Sienna at the same time?

It is strongly recommended. If one caliper on the Toyota Sienna has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your Sienna. Replacing both restores balanced, even braking and eliminates the risk of the second Sienna caliper failing shortly after the first is replaced.

Do I need to bleed the brakes on my Toyota Sienna after installing a caliper kit?

Yes. Opening the hydraulic circuit on the Toyota Sienna to install the new caliper allows air to enter. After installation, the brake circuit on the Sienna must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Toyota Sienna.

What is the difference between a new and remanufactured caliper in the Toyota Sienna kit?

A new caliper for the Toyota Sienna has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original Sienna housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Toyota Sienna applications.
