Hi,
I have an 88 GTA. It's possible the brake fluid is the original fluid.
I am working on my brakes, and noticed actual flecks of black "dirt" in the fluid in the master cylinder! I spooned some of it it out and examined it closely. When I rubbed the flecks , some dissolved back into the fluid, but some of them felt gritty and stuck to my finger. What the heck ?
Is this what happens to old brake fluid ?
Thanks
