Parts for your 2008 Toyota Crown-Brake wheel cylinders

2008 Toyota Crown – brake wheel cylinders: used or not?

Short answer: they’re not used. The 2008 Toyota Crown (S200 series – e.g., GRS200/201/204 and URS206) runs four-wheel disc brakes with hydraulic calipers, not drum brakes with wheel cylinders. This layout is documented in Toyota’s New Car Features (NCF) for the S200 Crown and the Toyota Electronic Parts Catalogue (EPC) for the same series, which list front ventilated discs and rear disc brakes with sliding calipers, plus a drum-in-hat parking brake. The drum-in-hat mechanism uses mechanical shoes operated by a cable, so there’s no hydraulic wheel cylinder involved there either.

Because the 2008 Crown is designed around disc brakes, a “brake wheel cylinder” simply isn’t part of its hydraulic hardware. Instead, braking force at each wheel is applied by a caliper piston (or pistons) squeezing the pads onto the rotor. This setup offers better heat management and pedal feel, and it integrates neatly with ABS and stability control. The Toyota workshop manuals and parts listings for S200 models reinforce that there’s a caliper at each corner and no listing for rear wheel cylinders on these passenger variants.

What to look after instead during servicing:

• Front and rear brake calipers: check for even pad wear, piston seal condition, and free-moving slide pins (clean and lubricate with the correct high-temp grease).
• Brake pads and rotors: measure rotor thickness and runout, replace pads before they’re at minimum thickness, machine or replace rotors if they’re out of spec.
• Brake fluid: flush and replace with the specified DOT fluid at the recommended interval (commonly every 2 years) to keep moisture and corrosion at bay.
• Parking brake (drum-in-hat): inspect shoe lining thickness, clean the hat drum, and adjust the shoe clearance/cable so it holds firmly without dragging.

Note: The Crown “Comfort”/taxi line is a different platform and has used rear drum brakes with wheel cylinders. This page covers the 2008 Crown S200 passenger models (Athlete/Royal Saloon types), which use disc brakes all round per Toyota NCF and EPC references.

Does a 2008 Toyota Crown have brake wheel cylinders?

No. The S200-series Crown uses disc brakes with hydraulic calipers at all four wheels. Toyota’s S200 Crown New Car Features and the Electronic Parts Catalogue specify disc/caliper assemblies and a mechanical drum-in-hat parking brake, so there are no hydraulic wheel cylinders on these models.

What should be serviced instead of wheel cylinders on a 2008 Crown?

Focus on the calipers (seals, slide pins), pads and rotors, and a timely brake fluid flush. Also service the drum-in-hat parking brake shoes and adjuster so the handbrake holds well without dragging. This routine care prevents uneven wear, sticking calipers, and soft pedal feel.

How can someone tell if their Crown has drum brakes out back?

Look through the rear wheel: a visible caliper over a shiny rotor means disc brakes. A solid backing plate with no caliper would indicate a drum. For S200 Crown passenger models, Toyota’s manuals and parts data show rear discs with calipers, not drums.
