All 4 brakes sticking and
Your braking problem could be from the diaphragm being torn inside the brake booster. If you are not losing fluid you should have that checked along with the hose that goes to the booster also, it may be soft and collapses when you apply the brakes. It connects to the manifold and uses vacuum to the power brake booster to apply and retract the master cylinder equally. The hose may be soft from being near the exhaust manifold and may need to be replaced. Also the check valve for the brake booster should be replaced if the hose is bad, it may have debris from the deteriorated hose.

1999 lexus sc 400 problems can I splice a new oem 02 sensor to existing wires?
Hello your question is a bit short on information, shooting in the dark here I am guessing you have the old 02 sensor out? If the connector
got damaged you can go right to NAPA and get factory type connector to replace the damaged one with. As a last resort you can carefully match each wire then reconnect them by soldering each one. Make sure you use small enough shrink tube and also slide it on the wire before you solder each wire so you can cover each one after its been connected and cooled.
Good luck and be safe.

What you are seeing is brake pad and rotor dust..the reason you do not see as much on the rear is because over 60% - 70% of a cars braking is done by the front wheels and the they get a much faster and heavier braking..the dust is the evidence...note many times it is how the driver driver stops the vehicle..a slow pumping the brake stopping will not get the build up or very little while a jack rabbit heavy braking driver will get it quickly. I am concerned about the oily part..if you are saying just an oily residue mixed with the dust is ok because it is a hydraulic system and there us cylinder weepingis normal..but heavier oil could mean Front cylinder leaking...and should be checked by a professional..good luck..
