Parts for your 2007 Toyota Blade-Brake wheel cylinders

2007 Toyota Blade — Are brake wheel cylinders used?

Short answer: no — the 2007 Toyota Blade doesn’t use brake wheel cylinders. The Blade (E150 series, including Blade and Blade Master) runs disc brakes at the front and rear, so it uses hydraulic calipers rather than the drum-brake style wheel cylinders.

Technical sources that specify rear disc brakes and calipers on the Blade include:

• Toyota New Car Features (NCF) for the E150 platform (Auris/Blade): Brake System — details 4‑wheel disc configuration with ABS, EBD and BA.
• Toyota Repair Manual (RM) for E150 series: Brake section shows “Rear Disc Brake (Caliper Type)” procedures, not drum brake service or wheel-cylinder overhaul.
• Toyota Electronic Parts Catalogue (EPC) for Blade/Blade Master: rear brake exploded views list caliper assemblies, pads, discs, parking brake shoes (drum-in-hat), but no wheel cylinders.
• JDM sales brochures/spec sheets for Toyota Blade (2006–2012): brake spec lines read “Front: Ventilated disc / Rear: Disc”.

Why wheel cylinders aren’t used on the Blade comes down to the brake design. Wheel cylinders are specific to drum brakes, where two pistons push brake shoes outwards onto a drum. The Blade’s rear brakes are disc type, so they use a sliding or fixed caliper with one or more pistons to clamp pads onto a rotor. While the rear rotor includes an internal drum for the mechanical parking brake (the “drum-in-hat” setup), that parking brake uses small shoes and a cable mechanism — not hydraulic wheel cylinders.

For owners, that means any rear brake hydraulic issues relate to calipers, hoses and lines, not wheel cylinders. Regular servicing should focus on pad thickness, rotor condition, caliper slide lubrication, seal condition, fluid flush intervals, and the parking brake shoe clearance inside the drum-in-hat. If someone suggests replacing “rear wheel cylinders” on a 2007 Blade, they’re likely mixing it up with a Corolla/Auris variant that came with rear drums in other trims or markets. The Blade’s upmarket spec sticks with discs all round.

Popular questions about 2007 Toyota Blade brake wheel cylinders

Does a 2007 Toyota Blade have brake wheel cylinders?
No. The Blade uses disc brakes at both ends, so it has calipers, not drum-type wheel cylinders. If you’re chasing a hydraulic leak at the rear, you’d be inspecting caliper seals and hoses rather than any wheel cylinder.

What should be serviced instead of wheel cylinders on a Blade?
Focus on rear calipers (slides, pins, dust boots and piston seals), pads and rotors, brake fluid condition, and the small parking brake shoes inside the rear rotor hats. A periodic brake fluid flush (typically every 2 years) and cleaning/lubing the caliper slides go a long way.

Could a Blade be converted to rear drums with wheel cylinders?
It’s uncommon and not recommended. The Blade’s braking performance, ABS/EBD tuning and parking brake arrangement are designed around rear discs. Converting to drums would be a step backwards in performance and complicate compliance and insurance.
