91 YJ clutch reservoir cap requires DOT 3 but the owners manuel suggests DOT 4. What gives? Also does anyone have the problem of the e-brake jumping out of locked position when on a slight slant? Thanks.
I would use DOT 5 . It is silicon based and you will never have to change it again . Plus if your master cylinder ever leaks like mine did it will save you a lot of grief . I lost all of the pain off of both sides of my firewall from the master cylinder seal failure where the brake pedal rod goes into the master cylinder . My drivers floor board is all rusted now . Time for some POR 15 paint .
