Review on 🔧 Dorman M390034 Brake Master Cylinder: Compatible with Mazda Models - Ultimate Replacement Solution by Jorge Bryant

1990 Mazda Miata My old brake lever was leaking a bit and the whole cylinder was starting to rust a bit on the outside. I replaced the whole thing, took a couple of hours, you need 10mm wrench to take it off. I had to remove the stock plastic air intake to make room for the slow removal and tightening of the brake lines. Don't forget to bleed all 4 brakes when replacing. No brakes = no fun. Safety first.
