Re: Dot 5 Fluid and CSSB Warning
This is a decal on Lone Star's boxes.
I quit using Dot 5 fluid probably 5-years ago, maybe longer. I have been care-taker for a persons collection of cars. Most have been sold off now, but he absolutely refused to use anything but DOT 5 fluid. Did not want to hurt the paint. So, about every 12 to 18 months, calipers would start to leak, bring it home, put new calipers on. Good business, especially for the brake people.
The 64, most of the time, would not last 12-months. Every spring, I would take apart the master cylinder, wheel cylinders and put new seals in. The old seals would look like your hands do after being water for a long time. All wrinkled up, swelled up, hard to remove.
The effect of DOT 5 on british cars is even more profound. They leak right away. Usually cannot get it out of the shop into the customers hands.
I was told it was a change in the seal compound, the rubber is not compatible to DOT 5. But, I do not know.
Ever wonder why NO car manufacturer uses DOT 5? I suspect it is more than the cost of the fluid.
I only have one can in the shop. It is an OLD OLD metal can used on Terrys car. It would be fun to have a chemical analysis done, see what has changed.
I use DOT 4 in everything now and do not have any problems. So much for job security?
