Description

This Wabco single wheel cylinder is a critical component within air brake systems, responsible for converting air pressure into mechanical force to actuate the vehicle's brakes. It's commonly used in commercial vehicles and trailers to ensure reliable stopping power. The cylinder features a cam-operated design with a boot for enhanced durability and a robust construction to withstand demanding operating conditions. Its OE specification ensures compatibility and performance, while the 127.0 mm diameter and 120.0 mm stroke contribute to precise brake control. This cylinder measures 155 x 470 x 155 mm and features M14 x 1.5 and M16 x 1.5 port threads. It operates effectively within a temperature range of -40°C to +80°C and is secured using a screwed yoke and 5x Ø 8.5 mm mounting points.

Key Features & Benefits

This little guy takes the air pressure from your brake system and turns it into mechanical force. Basically, it pushes pistons out which then press the brake shoes against the drum, slowing or stopping the wheel. Think of it as a converter – air pressure in, pushing force out. It’s a simple hydraulic cylinder, but working with compressed air instead of fluid. Each wheel on your vehicle, typically, has one of these – although some heavier duty setups will have dual systems. It’s part of the air brake system, which is common on larger trucks, trailers, and buses. It works directly with the brake shoes to actually do the stopping. It's a core component - without it, pressing the brake pedal won't actually do anything at that wheel.

Symptoms, Risks & Replacements

Well, if this fails, that wheel isn't going to stop reliably. You'll notice if one isn’t working – pulling to one side when you brake is a big sign, or maybe needing to press the pedal a lot further than usual. It’s a safety item, plain and simple. It's not something you want to put off repairing. It acts like a shield protecting you and others on the road. We carry a good selection of these, and you can find a lot of options over at Fixparts Online if you’re looking to compare. Replacing them is usually pretty straightforward, but if you're not comfortable working on brakes, definitely have a professional take a look.
