Hi,
As part of my frame off restoration I made new brake lines and new cylinders everywhere. Now I have the choice to go DOT4 (standard) or DOT5 (silicone). The car is a 35 year old Toyota Hiace which will be an everyday car doing approx 10000 miles a year. When disassembling the old parts I noticed corrosion on the brake master cylinder and the proportional valve in the regions closest to the "outside air" suggesting that standard brake fluid attracts water and this will be a problem if not changed often.
Does anyone have hands on experience using DOT5 vs DOT4 brake fluid and can help me choose a way forward?
