warf90 Posted February 11, 2007 Share Posted February 11, 2007 I am still trying to get my brakes right after the rear disc conversion and deleating the rear porportion valve. When I was pumping the brakes, the brake light came on in the dash and it will not go out. How do I get the light to go out? Thanks Link to comment Share on other sites More sharing options...
Rokhound Posted February 11, 2007 Share Posted February 11, 2007 the brake light on the dash on mine comes on if the ebrake is push down i would check that. Link to comment Share on other sites More sharing options...
500 MJ Posted February 11, 2007 Share Posted February 11, 2007 My old XJ had it come on when it was low on fluid, you might have messed something up when you messed with the prop valve...IDK Link to comment Share on other sites More sharing options...
carnuck Posted February 12, 2007 Share Posted February 12, 2007 Did you seal off the extra line going to the front? I did that with mine when I went to SOA and only 1 line to the rear. (I put a plug into the master cyl up front to block it off) Link to comment Share on other sites More sharing options...
Oizarod115 Posted February 12, 2007 Share Posted February 12, 2007 that light comes on if the pressure from front to back is different, mine came on once from the fluid level dropping, and even when filled up it took a month to go back off. brakes were fine though.

Eagle Posted February 12, 2007 Share Posted February 12, 2007 that light comes on if the pressure from front to back is different, mine came on once from the fluid level dropping, and even when filled up it took a month to go back off. brakes were fine though. x2 what he said ^^ The same light warns that the parking brake is on and that there is a pressure imbalance between the front and the rear. First step, as noted above, is to make certain that the parking brake isn't on, not even a little bit. Assuming that's okay, if the light is on either the front brakes or the rear brakes have air in the lines, or have a leak. Link to comment Share on other sites More sharing options...
warf90 Posted February 12, 2007 Author Share Posted February 12, 2007 The light went out, but I am still having issues with my brakes. I am certain that is was not the emergency brake. The reason I know is the light came on when I pushed the brake pedal and it went to the floor. It does that the first time you hit the brake, but after pump the brakes they are good. I also have plugged the bottem port on the block. So now I have just one new line going to the back with no prop valve. I know I have issues with the rear brakes because I clamped off the line going to the rear and I had great brakes. The rear brake set up I have is the TSM kit with the Cadillac eldo calipers and they are junk. This kit was on the rear axle when I bought it. I finally drove it around my house and when I pulled it back into the garage I could smell brakes burning. It was coming from the right rear. I am going to have to replace that caliper and see what happens next. Before driving I gravity bled and also bled the brakes by having some one pump them. I got no air out of the back at all. I am at a loss of what is wrong. Hopefully it has something to do with the right rear claiper. Either way I have to replace it because it is dragging.

87manche Posted February 12, 2007 Share Posted February 12, 2007 spngy pedal that pumps up? that really sounds like air in the lines. Link to comment Share on other sites More sharing options...
warf90 Posted February 12, 2007 Author Share Posted February 12, 2007 I agree with the air still in the lines. I have bled them alot. I have gravity bled and also had some one pump them up and still no air comes out. I am going to bleed them again once I replace the bad caliper and see what happens.

mjeff87 Posted February 12, 2007 Share Posted February 12, 2007 You're on the right track with the caliper. Have someone apply the brakes while you watch the caliper, and see if it moves at all. I'd bet the piston is seized/binding. Jeff Link to comment Share on other sites More sharing options...
carnuck Posted February 12, 2007 Share Posted February 12, 2007 caliper problem along with not enough fluid volume from the master cyl. IIRC there is an upgrade using a similar vintage E350 master cyl. Link to comment Share on other sites More sharing options...
