What can fail
On certain S10, S15, T10 and T15 models, the vacuum hose can detach from the brake booster check valve due to engine backfire. This causes higher idle speed and loss of brake power assist once the booster's vacuum reserve empties.
What the fix does
A clamp will be installed on the power brake booster hose where it connects to the brake booster check valve.
