How to Remove a Rusted Bleeder Screw
What we are discussing about is "filling" or pinning the hollow center of a brake bleeder valve when get rid of it. Why would you want to perform this? The answer is easy. This is performed to support keep the rusted bleeder screw from breaking when it is "frozen" in the caliper and you are trying remove or loosen it.
1. If you take a straw, grip one end, and twist the other finish of the straw the center of the straw will twist around itself. Think of a hollow air bleeder valve with the base of the bleeder control device rusted into the caliper. Think of what occurs to the bleeder valve when you use force with a wrench trying to loosen it.
2. Now fill the straw with water or sand and repeat this twisting test. You will find that the full straw now movies. In simple words, the straw does not collapse inner onto itself. Pinning a empty bleeder control device makes the equal effect.
3. Note the quantity of rust and scale on the base seat place of this bleeder. Bleeder valve chill up not just only their threaded place but also on the seat tapered the base of the control device.
4. This is what generally occurs to a frozen bleeder valve when it is try to be removed.
5. You can use most anything to fill the middle grip of a bleeder valve but a piece of soft welding rod jobs very well. Cut the piece slightly longer than the hollow length center.
6. Add the pin into the bleeder center and trap it download as far as easy. Do not hesitate if it is a bit long. The technique is to fill the center fully. The soft welding rod will just flatten itself onto the end of the control device.
7. Get a phoenix systems "Brake free" air hammer tool and locate a socket on it of the right size to fit the bleeder valve. Note: if you use a shallow socket will use more force on the frozen threads and seat than with a deep socket.
8. With the brake free tool linked to an air hammer add a Philips screwdriver or other similar instrument via the hole of the "Brake free" tool. Push downward firmly on the air hammer while pulling the active of the air hammer and use left hand rotational force to the "free brake" blade via the Philips screwdriver.
9. If you use heat to try to lose the bleeder valve the heat will travel into the caliper body itself and will get the area housing the caliper square cut seal. This heat may simply cause the seal to have issues. It is never a best idea to heat a bleeder control device to try and free it up. Do not perform it. The bad effects can be safely related. Granted, you will have to change the bleeder as it is almost not possible to get the pin out but that is little price to pay for successfully get rid of bleeder rather than having to change the full caliper.
