Hi, everyone. Sue here at 1A Auto. And today on our '03 Tundra, we're going to show you how to check your brake fluid at the master cylinder. If you need any parts for your car, click on the link below and head on over to

Hood release on this Tundra is located on the driver's side right at the knee panel. It has a picture of the hood. Pull on the cable. The safety latch is located to the left of the symbol. You'll feel the lever right there. You push up on it. Lift your hood up.

The brake master is located in front of the driver's seat. You've got your brake booster and the reservoir, and the cap on this Toyota—you can just pull up on it. There's no twisting or locking. As always, every brake master will have the actual type of fluid. DOT 3. Some will say four. Newer ones can be say up to five, but check your cap before replacing the fluid. There's a nice measurement on the side of the reservoir. It says max and low, minimal.
