Shop the best air brake systems
At Truckstop, our collection includes ABS brakes, quick release valves, relay valves and ABS sensors. Unlike hydraulic systems, truck air brakes use compressed air to deliver strong, consistent braking force required for long‑haul and high‑load applications.
ABS brakes play a crucial role in preventing wheel lock‑up, helping drivers maintain steering control, reducing stopping distances and improving overall safety. A functioning ABS sensor is essential for accurate wheel‑speed monitoring, and replacing worn sensors means the system continues to operate as intended.
Quick release valves are designed to speed up the release of air from the brake chambers, allowing brakes to disengage rapidly, reducing the risk of brake drag, which can lead to overheating and premature wear. These valves are particularly important in multi‑axle vehicles, where consistent timing across the braking system is required.
Relay valves control the delivery of air to the brake chambers. By positioning the valve closer to the chambers, air reaches the brakes more quickly, improving reaction times and ensuring even braking across the vehicle. A worn or slow relay valve can cause delayed braking, uneven performance or increased stopping distances, making timely replacement essential.
Truckstop provides air brake components that meet industry standards from the most trusted manufacturers. Whether you are replacing an ABS sensor, fitting a new relay valve or upgrading quick release valves, our range provides dependable solutions for workshops and fleet operators.
With UK nationwide delivery, Truckstop makes it easy to maintain the braking performance your vehicles depend on.
Frequently Asked Questions
What causes slow brake release in an air brake system?
Slow release is often linked to a failing quick release valve or restricted air lines. Replacing the valve usually restores normal operation and prevents brake drag.
How can I tell if an ABS sensor is faulty?
Common signs include ABS warning lights, inconsistent braking behaviour or loss of ABS function during hard stops. A diagnostic check will confirm which sensor needs replacing.
When should a relay valve be replaced?
A relay valve should be inspected during routine servicing and replaced if there are signs of delayed brake response, air leaks or uneven braking across the axles.
How can I tell if the air brake part will work with my truck?
Simple. If you add the item to your cart, and let us know your vehicle registration using the option on the cart page, we'll check the part fits before we process your order. If it doesn't match the vehicle, we'll get in touch to discuss your options.
