Parts for your 2008 Ford Falcon-Brake wheel cylinders

2008 Ford Falcon brake wheel cylinders — fitment, purpose and service advice

Whether brake wheel cylinders are relevant on a 2008 Ford Falcon depends on the variant. According to the Ford FG Falcon Workshop Manual (Section 206-00 Brake System) and dealer specification sheets for the 2008 FG sedan range, these cars use four-wheel disc brakes with hydraulic callipers and do not have brake wheel cylinders. However, the Ford BF MkIII Workshop Manual (2008, Section 206-02 Rear Drum Brake) and Australian parts catalogues from Bendix/PBR list hydraulic wheel cylinders for BF MkIII Falcon wagon and selected BF-series Falcon Ute variants that retained rear drum brakes. So: FG sedans in 2008 don’t use them, 2008 BF MkIII wagon and some utes do.

Why no wheel cylinders on FG sedans? They run disc brakes at all four corners, where a calliper squeezes pads onto a rotor. Wheel cylinders are a drum-brake part, they push brake shoes outwards against a drum. With discs at the rear, there’s simply no place for a wheel cylinder. The small “drum-in-hat” parking brake found inside some rear rotors is mechanical and doesn’t use a wheel cylinder either.

For owners of a 2008 Falcon that does have rear drums (notably BF MkIII wagon and some BF utes), the wheel cylinder’s job is to convert hydraulic pressure into outward shoe movement, giving strong, even rear braking. Because they live in a harsh spot, they can corrode or leak with age, especially on vehicles that tow, carry loads, or see lots of coastal kilometres.

• Common signs it’s time to replace: dampness or fluid weep under the dust boots, a soft or sinking pedal, the car pulling to one side under brakes, contaminated brake shoes, or uneven rear braking on a WOF/roadworthy test.
• Best practice is to replace wheel cylinders in axle pairs, fit new brake shoes if they’re soaked or worn, and machine/replace drums if out of spec.

Servicing tips for drum-equipped 2008 Falcons: inspect the wheel cylinders at every brake service, gently peel back the dust boots to check for fluid, renew brake fluid (DOT 4, not silicone DOT 5) every 24 months or 40,000 km, and bleed the system after any hydraulic work, typically starting at the wheel furthest from the master cylinder (often RR–LR–RF–LF on RHD Falcons—confirm with the workshop manual). After refitting, adjust the shoes so the drum just clears without drag, then bed the brakes in over a few gentle stops.

If unsure which brakes the vehicle has, a quick look behind the rear wheel will tell the story: a large enclosed drum means there’s a wheel cylinder, a visible calliper and rotor means there isn’t. VIN/build codes in the Ford service information also identify the rear brake type.

Popular questions about 2008 Ford Falcon brake wheel cylinders

Does a 2008 Ford Falcon have brake wheel cylinders?
It depends on the model. 2008 FG sedans use four-wheel disc brakes, so there are no wheel cylinders. The 2008 BF MkIII Falcon wagon and some BF-series Falcon Ute variants run rear drum brakes, which do use wheel cylinders.

How can someone tell if their 2008 Falcon has rear drums or discs?
Peek through the rear wheel: a drum is a closed round housing with no calliper, a disc setup shows a rotor with a calliper. Owners can also check the build plate/VIN details against Ford service data or a reputable parts catalogue to confirm.

What maintenance applies to wheel cylinders on drum‑equipped Falcons?
Inspect at each service for leaks or seized pistons, renew brake fluid every 2 years/40,000 km, and replace cylinders in axle pairs if one side is leaking or sticking. After replacement, bleed the brakes and adjust the shoes correctly for consistent pedal feel and even braking.
