While changing the brake pads on my 2007 Sequoia, I accidentally removed the bolt that holds the two halves of the calipers together. Brake fluid poured out. I tightened the bolt back on and finished installing the pads. After finishing, I noticed that my brakes felt very mushy and were barely stopping my car. Along with that, my parking brake light and traction control light stay on. I decided there was probably some air in the brake lines, so I bled them. But nothing changed. I still have very mushy brakes with all of these lights on my dash popping up. Any ideas? Thanks
what a bunch of lies and crap. Well trained riders can ride for years without a helmet. go to the A.B.A.T.E. website they have stats on all kinds of good stuff. Only thing mandatory helmet laws are good for, are the helmet companies, and the politicians they give money to.
i would say bleed them some more sounds like you still have air in the system. be sure to top off the master cylinder, it could be low there too.
bleed them more i have helped my husband with brakes quite a bit and removing the calipers is no big deal you have to if you are going to change the roter hopefully you have help and someone can push the brake while you bleed them they hold the brake completly down until you tighten the bolt back also check the brake line one time when we changed brakes the brake line busted nothing that we did the brake line was rusted really bad we had just got the vehicle too
I would re-bleed the brake system. Farthest point to closest point. If this doesn't resolve the issue, check the caliper that you removed the bolt from that leaked fluid. Is it still leaking? When it did leak, did it saturate the rotor, or did any get on the new pads? If it got on the new pads, you will need to replace them with new ones. If on the rotor, you will need to use brake clean and spray and wipe the brake fluid off. Next, when you removed the bolt that retains the dual caliper setup, did the caliper seperate completely? If so, and you put the caliper back together to fasten the bolt, you could have damaged one of the seals. If you did, you will need to have that caliper re-built to seal properly, so no brake fluid will seep out and cause low pressure on the braking system. If brake fluid seep's out, it will saturate the new pads, sensor, and the rotor, possibly causing brake failure. You also want to be sure you didn't get any brake fluid on the sensor, if so, you will need to clean it off before reassembly. To clear the lights, you can try to disconnect the battery for a few minutes and then re-connect it. If it doesn't clear, you will need to go to your local parts place. They will have an OBD scanner that will hook up under your dash and relay any codes that you have. Read the codes, make sure they only pertain to your braking system, if so, they can clear them, resetting your computer and sensor's. If you have anything other than braking codes, you will need to look into them further for the repair.
