Parts for your 2004 Toyota Highlander-Brake calipers

2004 Toyota Highlander brake calipers

Yes, brake calipers are absolutely relevant to the 2004 Toyota Highlander. Toyota’s factory repair literature for the XU20-series Highlander/Kluger (Brake System – BR section) specifies floating-type disc brake calipers on the front axle across all grades. Toyota’s electronic parts catalogue (EPC) also lists front caliper assemblies (Toyota caliper part numbers typically begin 47730 for LH and 47750 for RH on this platform). Major technical catalogues from Bendix and other aftermarket suppliers likewise list calipers, seal kits, slide pins and hardware for the 2004 Highlander/Kluger. Many V6/AWD variants also use rear disc brakes with calipers, while some 4‑cyl FWD models have rear drums.

On this Highlander, the caliper’s job is simple but vital: it squeezes the brake pads against the rotor to slow the vehicle. A floating caliper slides on guide pins so it can clamp evenly from both sides. Because calipers live right by the heat and grime at the wheel, they need a bit of love to keep braking smooth, straight and quiet.

For servicing, a sensible owner or workshop will:

• Inspect calipers at each service or when rotating tyres — look for fluid leaks, torn dust boots, uneven pad wear or a frozen slide pin.
• Clean and lubricate the slide pins with a quality high‑temp silicone brake grease at every pad change (or roughly every 20,000–30,000 km in harsh conditions).
• Replace the copper crush washers on the hose banjo bolt whenever a caliper is removed.
• Bleed the system after any hydraulic work and keep to fresh DOT 3 or DOT 4 fluid, changing brake fluid about every 2 years helps prevent internal corrosion and sticking pistons.
• Check the flexible brake hose for cracks, kinks or swelling, and renew if suspect.
• Refit hardware and tighten to the Toyota torque specs from the repair manual, don’t guess with a spanner.

If a caliper is seized, leaking or badly corroded, replacement is usually the smart play. Many choose to replace calipers in axle pairs to keep braking even. Match pad compound left-to-right, bed-in new pads and rotors properly, and take a short, careful test drive to confirm there’s no pull, drag or overheating. For NZ and Aussie owners, note the same hardware is commonly catalogued under Toyota Kluger for local markets, but the fitment and maintenance approach are the same.

Does a 2004 Highlander have rear brake calipers?

It depends on the variant. V6 and many AWD models run rear disc brakes with calipers, while some 4‑cyl FWD models use rear drum brakes (no rear calipers). A quick peek through the rear wheel or checking the VIN/axle specification will confirm what’s fitted.

How often should the calipers be serviced?

Inspect at every service, lubricate slide pins at each pad change, and refresh brake fluid about every 2 years. If the Highlander tows, sees lots of hills, or does city stop‑start, shorten those intervals.

What are signs a caliper needs replacement?

Pulling to one side under braking, uneven pad wear, fluid leaks, a hot wheel after a drive, a dragging feel, or a burnt smell are common giveaways. Torn boots or rusted pistons also point to rebuild or replacement.
