1995 GMC Jimmy Q&A
1995 GMC Jimmy Question: Brakes go all the way to floor w/o stopping.Warning light comes on.
When you open your hood,standing in front of your truck on the right against the firewall you will see your master cylinder which has brake lines coming out the side. The cover snaps off lifting the side tabs to open the cover. If the brake fluid is down,add fluid and make sure rubber seal is on cover first and then tap the edges of the cover down till it seals. Pump brakes several times while it's running and look under vehicle to see if there are any leaks.If the truck is originally from texas,it could be a wheel cylinder,brake hose or front caliper leaking. - Hightec1
