Signs your brakes need attention
Catching brake wear early keeps trucks safe, legal and on the road.
Air leaks or hissing
Audible leaks at chambers, valves or lines, or slow pressure build-up.
Low-air warnings
Warning light or buzzer, or pressure dropping faster than normal.
Pulling to one side
Uneven braking can mean a sticking caliper, worn lining or bad adjustment.
Longer stopping
Extra pedal travel or longer distances often point to out-of-adjustment brakes.
ABS light on
Often a failed wheel speed sensor, damaged harness or modulator fault.
Heat, noise or vibration
Grinding, squealing, pulsation or hot hubs can signal worn friction or cracked drums.
Safety first: brakes are safety-critical. Have any brake problem inspected and repaired by a qualified technician, and follow the vehicle and axle manufacturer's specifications.
Brands we cross-reference
Send us an OE or competitor part number and we'll match it.
Frequently asked questions
What brake parts do you supply for trucks and trailers?
We supply air disc brake pads, brake shoes and relining kits, drums, rotors, brake chambers, automatic slack adjusters, air dryers and cartridges, relay and other air brake valves, ABS components, calipers, S-camshafts and air lines for North American and European trucks and trailers.
Do you sell OEM or aftermarket brake parts?
Both. Tell us the part and your vehicle and we will quote OEM and aftermarket options so you can choose on price and quality.
How do I find the right brake shoe kit, drum or chamber?
Send the vehicle make, model and year, the axle make if you know it, or the part number stamped on the old part (for example 4707Q shoes or a 30/30 chamber). A VIN helps too. We confirm fitment before you order.
What do the prices on this page mean?
They are averages of new-part prices listed by US truck-parts dealers and online stores, shown as a market guide. They are not our price list. Add a part to your quote and we will send our price.
Can I get a quote for several brake parts at once?
Yes. Add each part to your cart, then send the cart as one quote request with your contact details and location.
Have a part number?
Send it over and we'll quote a matching aftermarket part.
