Piaggio 227549 Rear Brake Cylinder Ø 19 mm – Ape 50 Mix, Ape Poker Petrol and Diesel, Quargo

The Piaggio 227549 rear brake cylinder is the hydraulic cylinder that pushes the brake shoes against the drum. It is an original Piaggio spare part with a 19 mm diameter for Ape 50 Mix, Ape Poker petrol and diesel, and Quargo, and comes complete with dust boots and bleed screw already assembled (observed from product photographs). On a work vehicle that carries loads, this is not just any spare part: if a cylinder leaks, that wheel stops braking, and the vehicle pulls to one side when braking.

✓ Strengths

• Original Piaggio spare part, catalog code 227549 — same bore and same mounting distances as the original equipment part
• 19 mm diameter: this is the dimension that determines the pushing force on the brake shoes. A cylinder of a different diameter changes the braking balance even if it fits the holes
• Rubber dust boots already assembled at both ends: these keep water and dust out, and this is where cheaper cylinders fail first (observed from product photographs)
• Bleed screw already assembled with its rubber cap: ready to be bled as soon as it's connected (observed from product photographs)
• Hose connection protected by a transport cap: the interior arrives clean and dry, as a hydraulic component should be (observed from product photographs)
• Cast body with two pre-drilled mounting holes: mounts on the brake shoe backplate without adaptations (observed from product photographs)
• On a work vehicle, it is a safety component: here, the original is not an aesthetic preference

Vehicle compatibility

Compatibility list from the official Piaggio spare parts catalog. If your vehicle does not appear in the table, contact us for more information before ordering: we will verify it in the catalog.

On a work Ape or Quargo, the rear brake does most of the work, especially when fully loaded. A leaking cylinder can be identified by three things: a pedal that sinks, fluid level dropping in the reservoir, and a damp halo on the back of the wheel. If you have even one of these, the part needs to be changed. We ship within 24/48 hours from Cercola. If you need a pair or also the brake shoes, contact us for more information.

Perfect for

• Those who find the brake fluid level dropping with no visible leaks elsewhere
• Those who have a long or spongy brake pedal even after bleeding
• Those who have seen a damp halo or drops on the brake shoe backplate when removing the wheel
• Those whose vehicle pulls to one side when braking: often it's a seized cylinder or one that isn't pushing
• Workshops and fleets that maintain Ape, Poker, and Quargo: it's a wear-and-tear item on working vehicles

Frequently Asked Questions

What is its diameter?
19 mm. This is the original size for the models listed in the table and is the first data to compare if you have already disassembled the old one. The diameter determines the force the cylinder exerts on the brake shoes: mounting one of a different size unbalances the braking even if it mechanically fits.

What is the yellow cap for?
It is a transport protection cap for the brake hose inlet hole (observed from product photographs). Keep it on until the exact moment you screw in the fitting: it ensures the cylinder arrives clean and dry inside.

Should I change one or two?
Two, those on the same axle. They have the same age and mileage: changing only one results in unbalanced braking and will require you to disassemble everything again in a few months. If you need a pair, please contact us.

How do I know it's the cylinder and not something else?
Three signs: the fluid level drops with no visible leaks on the hoses, the pedal sinks even after bleeding, and when removing the wheel, you find a damp halo on the backplate or the friction material. If the friction material is wet with fluid, the brake shoes also need to be changed: once saturated, they will no longer brake effectively.

Are the boots and bleed screw included?
Yes, they come pre-assembled: two rubber dust boots at the ends and the bleed screw with its cap (observed from product photographs). You don't need to retrieve anything from the old one.

Do I need to change all the brake fluid?
Yes, and this is the most useful advice on this page. Brake fluid is hygroscopic: it absorbs moisture from the air, and that moisture is what corroded the old cylinder from the inside. Putting old fluid back into the new cylinder means restarting the countdown.

Is it suitable for my Ape RST or FL?
The table above is the official Piaggio catalog list for this code: Ape 50 Mix, Ape Poker petrol and diesel, Quargo. Some retailers also associate it with RST Mix, FL2, and FL3: contact us for more information with your model and year, and we will confirm it before your order.
