I replaced my 2001 Lexus is300 with a brake booster delete. I need help with the adapters, I cannot find out what size I need and what the brake line nuts are. The sizes coming out of my new brake booster cylinder are 1/2 and 5/16 . So I just need to figure out the size of the stock lines and then get a adapter to thread them into my new brake master cylinder ! If anyone can help, I’ve been stuck on it forever because my town has no automotive shops.
