CONT
Only refer to this customer complaint after a complete check using the XR25.NOTES
Check the calipers, drums and bearings are not seized.
Check that the tyres are not under-inflated.
Check the coolingCheck that cooling is not insufficient.
Check the canister bleed
Disconnect the pipe connecting the canister bleed solenoid valve
to the inlet manifold.
Plug the pipe to prevent an air leak.
If there is no other effect, the canister bleed is faulty.
Check the axle assemblies
