I have a friend who had a problem with brakes hanging, He bought 2 rear wheel cylinders, I change out for him. Tried to ge him to Service Manual, He got Front Calipers and Pads instead. I installed for him. Then He bought Master Cylinder, He changes it. Still hangs, It has another unit with electronics at Master Cylinder. Any tests or input you can suggest.
TX? Thanks.
I think he will put out for the Manual Now. People don't understand the amount of Time and Parts that can be saved by a Manual.

Brake Fluid Looked watery/contaminated. It will do good for new fluid.

Brake pipes sometimes need to be replaced, if there's corrosion. This is particularly important on ABS systems. New tests focus on copper ions in solution (byproduct of brazing), as an indication of whether or not the brake fluid is good. Corrosion protection is one reason brake fluid should be changed every 24 months.

Litmus test strips are available to determine cororosive propeties within systems, but if known foreign substances have been introduced...... umm, why??
Mineral spirit flushing may be the only option, and only that, in an attempt to restore....
