Cbailey1389 Posted January 12, 2017 Report Share Posted January 12, 2017 Hey guys. New to the forum and to the sss world. I've searched countless posts but I wanted another opinion Truck is 04 awd sss with disc all around. Braking seems very diminished overall with a spongy pedal feel When I pump the brakes with truck running I can't build any pressure...with the truck off after 3 brake pumps the pedal is rock solid...when I come to a complete stop I can continue to push the pedal to the floor bud it does take considerable effort to do so. Any ideas? Thanks in advance Quote Link to comment Share on other sites More sharing options...
SS-GTP Posted January 12, 2017 Report Share Posted January 12, 2017 I'm assuming this SS is a recent purchase and you don't know the service history or is this a vehicle you have had awhile and this problem has just recently developed? If you just recently acquired the truck with the issue I would probably start with taking to someone that has a Tech2 or similar device that can do the anti-lock bleeding procedure. This procedure can't be done with traditional brake bleeding methods. Quote Link to comment Share on other sites More sharing options...
Cbailey1389 Posted January 12, 2017 Author Report Share Posted January 12, 2017 That's correct...new purchase and unknown history. I'll look into the brake bleed Quote Link to comment Share on other sites More sharing options...
1981evildisco Posted January 12, 2017 Report Share Posted January 12, 2017 Does the fluid need replaced? Maybe you can hit 2 bird with one stone. After bleeding with a Tech 2 i would look at bleeding them normally as well as checking for leaks. Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted January 13, 2017 Report Share Posted January 13, 2017 When I replaced my solid lines with stainless steel I used the "Gravel road ABS bleed" trick. Worked pretty good. Run your truck down a dirt or gravel road at 25 to 30 MPH and do 4 or 5 hard brake stops, (Or at least slow downs). You want the ABS system to engage, then re-bleed the system. It worked very good on my 03. If further bleeding doesn't resolve your problem; Check the master cyl. Quote Link to comment Share on other sites More sharing options...
NolletSSS Posted January 18, 2017 Report Share Posted January 18, 2017 The gravel road trick did not work when I had the OP's same problem. My truck just didn't have the stopping power to lock up the brakes even on a gravel/dirt road. I bled the brakes and bled them and bled them some more, with the same spongy pedal on the floor results. The only way you can firm up the brakes and get stopping power again is with a tech II or similar device (Snap-on) that will allow you access to run the self bleeding procedure for the anti-lock brakes. I ran the bleeding procedure about 9 times before I had a nice firm brake pedal again. Be sure to do one final bleed at all 4 corners again to get all the air-junk fluid that was pushed out of your anti-lock brake system. When you run the bleeding procedure you will hear the anti-lock brake system pump and the pedal will actually push you back into your seat. Run it as many times as it takes to get a firm pedal back and then run it again just for shits. If you take it to a shop to do it just make sure they don't stop after running it just once. It only takes a few minutes for the self-bleed to complete, and the only labor involved is to step and hold pressure on the brake pedal when commanded to do so. Fresh fluid is always a plus Quote Link to comment Share on other sites More sharing options...
