I am replacing the master cylinder and rear brake cylinders on my son's 1999 Durango. I want to get a line wrench set to help avoid stripping the nuts. Its the original master cylinder with 202,000 miles and 20 years of use. Hoping its either SAE or metric and not both for these nuts so I don;t have to buy two sets of wrenches. Does anyone know which it is? TIA.
