Kia Rio replacement parts
Kia Rio Brake Wheel Cylinder Wholesale
Rio rear wheel cylinders belong to confirmed drum-brake assemblies. Compare bore, mounting bolts and the brake-pipe union.

Brake Wheel Cylinder: application and selection
| Check | What to send |
|---|---|
| Assembly identification | Rear drum bore, mounting bolts and hydraulic pipe union |
| Vehicle record | Generation, production date, body market, engine and transmission; axle or side where relevant. |
| Component evidence | Overall, label, connector and mounting views; measured dimensions where they distinguish the assembly. |
Do not apply a drum wheel-cylinder reference to rear disc brakes. The cylinder must match the backing plate and shoe system, not just the model year.
Compare the connected components
For rear drum equipment, compare Brake Shoes, Brake Drums and brake wheel cylinder against one documented backing-plate assembly.
For a mixed system request, use the Brakes, Steering & Driveline guide. Resolve body and regional differences with the Rio generation and body record.
OE identification example
| Reference | Limited application |
|---|---|

Use the number only within this application boundary. Confirm the installed reference and vehicle record before order approval; the representative image is not proof of the numbered item.
