Master Cylinder Paint

[SS427]

Up until recently, I have used Dot 5 in EVERY restoration I have done since I started at Corvette Specialties in 1981. In reality, the only issues I have ever had were a slightly spongy peddle (likely due to the air bubbles) and Dot 5 is MUCH more prone to seep fluid than the Dot 3 due to it's viscosity. I have had some that flat refused to stop seeping no matter how tight I got the fitting. It will also bleed past the wheel cylinder rubbers in some cases. The only reason I recently went back to Dot 3 is because none of the resleeving companies will warrant their rebuilds if you use Dot 5 and virtually every car I do today has one or more sleeves between the master cylinders and/or wheel cylinders. If not for that I would continue to use Dot 5 as it is SOOOOOOOO much safer on the painted surfaces.
