What's wrong, in plain English

In some Toyota Tacoma trucks, the brake master cylinder was not machined properly during manufacturing. This improper machining can damage one of the seals inside the master cylinder. A damaged seal can reduce how well the brakes work, which means the truck may need a longer distance to come to a stop. This reduced braking performance can make it harder to stop the vehicle as quickly as normal.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your Tacoma is included.
2. Contact a Toyota dealer, or call Toyota customer service at 1-888-270-9371, to schedule the repair.
3. The brake master cylinder replacement is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 18V888000.
