Frequently Asked Questions (FAQs)

1. What size is the screw on a brake bleeder?

The standard size for a brake bleeder screw is 1/4"-28 x .92". This size is commonly used for brake bleeder screws in both standard (SAE) and metric measurements.

2. What size are brake bleeder nuts?

Brake bleeder screws usually have 8mm or 5/16" nuts. However, the screws holding the rear wheel cylinders (if drums) may have a 10mm hex head for removal.

3. What size is the GM bleeder screw?

The GM bleeder screw size is M10-1.5 x 27.55mm. This size is specific to GM vehicles and may not be compatible with other makes or models.

4. What size tube fits on bleeder screw?

The tubing used for bleeding the brakes should securely fit over the bleeder opening. It is recommended to use a clear container with a small opening (about 3/16 inches to 5/16 inches in diameter) for the vinyl tube to fit through. This allows for better visibility of the fluid quality and volume.

5. How tight do bleeder screws need to be?

Bleeder screws should be tightened with a torque of 24 to 48 in/lbs, which is just slightly more than hand tight. It only takes a ¼ to ½ turn to open or close the screw. It is important not to over-tighten the bleeder screw to avoid damage.

6. Do you bleed brakes with reservoir cap on or off?

When bleeding the brakes, it is recommended to leave the master cylinder cap unscrewed but resting on top of the reservoir. This allows for proper fluid flow and prevents pressure build-up in the system.

7. What does a bleeder screw look like?

A bleeder screw is typically a hexagonal or square knob located on a small round protrusion. It is commonly found at the top of the radiator on the side of the inflow pipe. The appearance of the bleeder screw may resemble a key used to wind a clock.
