Okay so I've search high and low for this...

I am trying to replace my prop valve, brake master cylinder, and front calipers on my 91 Si. I need to know if i can do this with my ebrake on. My driveway has a bit of an incline and if I dont have the ebrake on it'll role. The rear brakes are drums.

Thanks!

 

So throw some wheel chocks behind the rear tires. Only cost a few bucks. Otherwise throw something else that will prevent it from rolling.

 

E-brake is cable actuated. Nothing to do with your prop valve, m/c, or front calipers. Go ahead.
