Everything You Need To Know About Screw Kit

Air is highly compressible whereas fluids are incompressible and having air in a braking system line can render the hydraulic action nullified and therefore the removal of air from the brake line is mandatory and also recommended. Therefore, a brake bleeding screw is given. The brake bleeder screw is a screw that sits on top of the brake caliper to allow old brake fluid and air to be removed from the brake system. Brake bleeder screws, once loosened, are designed to release air and brake fluid out when brake pressure is applied. A bleed screw is a device used to create a temporary opening in an otherwise closed hydraulic system, which facilitates the removal of air or another substance from the system by way of pressure and density differences.

Screw kit as brake bleeder screw can come in a range of screw sizes from 3/16” to 7/8”. They can be provided in various coatings and surface treatments, brass seat inserts, and bleeder screws with O-rings. Bleeder screws are also used in coolant systems to bleed air. They are mostly fitted on the coolant hose. The hydraulic clutch also has a bleeder screw known as a clutch bleeder screw.

• The system becomes air-free by the use of the bleed screw.
• If there is no air in the brake system, the efficiency of the brake is increased.
• Bleeder screw is fitted on the front brake caliper and on the rear wheel cylinder.
• Bleeder screws make it easy to remove air.

As the air is lighter, the bleed screw is fitted at the top of the front brake caliper. There's a hole in the top of the bleeder screw where a clear hose is attached so as to observe the fluid/air coming out, and a hex section for screwing it in and out with a spanner. The caliper has a threaded hole for screwing the bleed screw into. The bleeding process basically involves applying brake pressure, slightly loosening the screw - about 1/4 of a turn - to raise the end of the screw and allow air and fluid to flow into the hole at the bottom, through the screw and out the hole at the top. The screw is then tightened again and the brake lever released, drawing in more fluid from the reservoir and the process repeated until there is no more air left in the system.

• If the bleeder screw is left loose brake oil will leak.
• Dust can block the hole of the bleeder screw if the dust cap is not fitted.
• Over tightening of the bleeder screw can cause damage to the caliper thread.
• The hex of the bleeder screw can get damaged, if the proper size of the spanner is not used.

There are a number of skilled auto mechanics who have the goal of opening their own car repair shop at some point in their careers. But let’s face it; if you want to put up an efficient as well as profit-making shop, then you might need much more than mechanical skills. There are a number of tools that you might need to perform the car repairs quickly as well as reliably. Auto repair equipment that you will need with Screw Kit may include:

• Spanner Set
• Brake Bleeder Bottle
• Transparent Hose

For replacing the brake bleeder screw kit, labor would cost about $40 to $60, depending on the type of vehicle and the quantity of bleeder screw which has to be replaced. To remove the brake bleeder screw kit, other related parts may have to be removed first; the total time for this kind of rework would take about 45 to 90 minutes.

Park the vehicle on level ground and pull the hand brake for safety reasons. Steer the car on the right side and remove the damaged brake bleeder screw by loosening it in an anti-clock direction. When removed immediately refit the new brake bleeder screw as the brake fluid will start flowing. Tighten the screw and clean the brake fluid. Top up the brake fluid reservoir with the recommended grade oil. Repeat the same for other wheels if the brake bleeder screw is damaged. There is a slight possibility that air may be in the brake system. To remove the air from the brake system, first. Connect a pipe to the brake bleeder screw. Put the other end in the bottle. Ask another person for help. The bleeding process basically involves applying brake pressure. When the pressure is applied, slightly loosen the screw about 1/4 of a turn to allow air and fluid to flow into the bottle. Then tightened again and released the brake lever, drawing in more fluid from the reservoir and repeating the process until there is no more air left in the system. Keep a check on the brake oil reservoir while brake bleeding.
