The necessary homemade product from old brake pads
When replacing brake pads, it becomes difficult to press in the protruding brake cylinders. To push them into place you have to use a hammer, pry bar and other improvised means. Naturally, such vandalistic methods cannot be called acceptable. It is much faster, more convenient and safer to press in disc brake calipers using a press that you can make yourself. This is a very cheap homemade product in terms of production, requiring only a grinder, a drill and a welding machine. The most important thing is that this device is made almost from rubbish, namely from already worn out brake pads, which are usually simply thrown away.
The top eye of the old brake pad needs to be cut off.
Then a hole with a diameter of 14 mm is drilled in its center for a bolt. Since the steel is thick, it is better to start with a thin drill, and only then expand the hole to the required size.
Next you need to weld a nut to the block around the hole made.
In order for everything to turn out smoothly, you should screw one nut onto the bolt, insert it into the hole and tighten it with the second nut. After this, one of them is thoroughly scalded.
In the future, the weld will be subject to stress, so spot tacking will not be enough. If you have an M14 tap available, then it is better to cut a thread in the block before welding; of course, before doing this, a hole is made in it with a 12 mm drill.
The bolt and second nut are removed, and the beginning of the thread is sharpened to make a cone.
Then 2 nuts are welded to its head to create a wide handle for easy finger tightening. If there are no extra nuts, you can simply turn the bolt with a wrench.
The modified bolt is screwed into the block, and the press is ready.
The only thing is that when trying it on, it may turn out that the block is too wide, then it will need to be cut off at the edges, but this can be solved in 2 minutes.
To use the press, you need to use a backing, which can be another old block. The device is installed in the caliper, rests, and presses the cylinder through the lining when the bolt is tightened. Having sunk it completely, the press is removed and a new block can be installed.
This is a cheap device in terms of manufacturing, assembled in 30-40 minutes, which can then be used for years. It will fit most cars with disc brakes, with rare exceptions when the cylinder needs to be turned as well as pressed in.
Materials:
- old brake pad;
- bolt M14 120 mm;
- M14 nuts – 3 pcs.
