87Warrior Posted March 25, 2009 Share Posted March 25, 2009 In reference to your 'pedal to the floor and e-brake light' situation. This exact scenario happened to me driving the Rubicon. Turns out my front drivers side brake hose burst open. Had fluid all over the place. [more of the story, do not buy the RE stainless brake lines] On the MJ's I do not think there is anything in the 'combination valve'. It is wide open and free flowing front/rear. That load sensing valve takes over the job. I would suggest inspecting the lines then bleed the system until NEW fluid runs out of all 4 bleeder valves.

james750 Posted March 26, 2009 Share Posted March 26, 2009 Ok.. I have an idea.. I could be 100% wrong but? I am thinking that when we "Recompressed" the Caliper Piston it caused something to go bad in the Combination Valve I am basing this on the following image: http://econtent.autozone.com:24999/znet ... pg/1.image Now.. anyone know where/how to get a replacement one? I doubt that it is the combination valve. Based on what I have been taught on brakes in school. on the rare instance that the combo valve gets clogged when you compress the piston into the caliper it will be a full brake application to 100% failure in an instant after you pump the pedal a few times during test drive. I've never seen it happen in the 30+ brake jobs I have done so I am not 100% sure on what it will look like. Based on what I am hearing most likely you need to bleed your brakes and if that doesn't fix it look for fluid leaks. I definitely sounds like a problem due to losing fluid or air in your brake lines (Because air is compressable it will compress before pushing your piston out causing you oto need to pump to build up the pressure needed to overcome the air compressing and actually push in the caliper piston).

Qui Gon-Jinn Posted March 26, 2009 Author Share Posted March 26, 2009 Headed for the local Jeep JY this morning. I talked to them yesterday.. the Valve is $20.. but going to look for a new Master Cylinder and booster.. maybe even a double booster??? Link to comment Share on other sites More sharing options...
