Can break master cylinder (kit) do as good job as a new master cylinder?
This is a Yes, and No reply.
if the mechanic insures that the bore of the brake master cylinder, is free of rust pits, and if not, uses a brake hone to smooth out the bore. Closer inspection will reveal if the pits are too deep, and the master cylinder is unusable.
if the rubber components that go into the bore of the brake master cylinder, are installed in the correct direction, all the components are assembled in the correct order, and are pre-lubed with a little bit of clean brake fluid, before installing.
if any of the above criteria is not met.
The main thing is that the Brake Master Cylinder is in good repair. In good shape. If we are discussing the original brake master cylinder, for a 1981 Ford F100 pickup truck, we are discussing a master cylinder that is 28 years old, and has seen a lot of wear.
As a metallic object, such as a brake master cylinder heats up, (Engine heat, or even just the sun shining on the vehicle), then cools down, the moisture that is always present in the air, will form in the master cylinder.
Forms in droplets, at the bottom of the master cylinder's reservoir. This moisture creates rust, when it touches the cast iron brake master cylinder casting.
The rust clogs the ports at the bottom of the reservoir, and goes down into the bore of the master cylinder.
Makes rust pits in the bore, and harms other master cylinder components, then goes into the brake lines, and onto the rest of the brake system.
For the cost of a rebuilt or new brake master cylinder, compared to the expense of the master cylinder brake kit, and your labor time, I would go with a rebuilt, or new one.
Also this is part of the Brake System, and there's no fooling around with brakes! Your life and/or someone else, Depends on those brakes!
