Bleeding brakes on any vehicle can be a tedious job and will take two people. You can spend a few dollars to make your own power brake bleeder, or you can purchase one ready made. The ready made bleeders are similar to the DIY power brake bleeders. With a little time and a few recycled items you can make your own power brake bleeder with a brake fluid catcher.

Tips and warnings
- Rather than buy a pneumatic pressurised cap, you can make your own from any master cylinder cap. Drill a hole in the middle and attach a brass nipple with a nut and washer. Use RTV to create a seal on the inside up to the brass fitting. Attach the brass tee as per earlier instructions.
- If your brake cylinder has a different type of top you can still create your brake bleeder. Find a master cylinder cover like yours, follow the above instructions to create the pressurised top.
- To keep from bleeding your brakes to the ground use an empty soda bottle, preferably the 680gr size or larger. Drill a hole in the middle of the cap, stick a length of hose about halfway into the bottle securing the cap and the other end of the hose to the brake line. Using a wire hanger or other similar wire, make a hanging hook by looping one end around the bottle and bending the other so it hangs off the axle.
- Use caution when drilling the caps. Begin with a small bit and work up to the size of the brass nipple.
- Do not dispose of brake fluid in the yard, trash or waterways. Take the fluid to a recycling centre or mechanic. Wash all containers before disposing of them.
- Use caution if you have an allergy to chemicals. Wear rubber or plastic gloves designed for the job.
