no

It is important though not harm much would be caused even if you don't do. this is because, when athe brakes to the front wheels, you might tamper and cause imbalance which exposes your car to risk. And so, to be on the safe side, you better avoid this.

Sounds like the vacuum line to the booster is damaged or the booster is bad. A large vacuum leak will cause the engine to stall (not run).

Several possibilities; low brake fluid level (check and refill as necessary), low / worn brake pads (replace as required), fluid leak in system; leaking brake lines, flexible brake lines in front.

Bring it to a skilled mechanic right away if the light goes off but the pedal sinks to the floor.

Possibly rotors resurfaced or replaced. They make a compound you smear on back side of disk pads to help with squealing and chatter. Sticking as far as brakes stay on? You will need to check calipers for any leaks and buy a good synthetic brake fluid for bleeding the calipers after installation. A caliper piston depression tool that works would be another good idea, and some brake cleaner spray to remove oil from rotors.

Check on-line for the many parts supply sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the front brake pad set from around $3.00, the brake calipers from around $11.00 (each), and the brake rotor from around $13.50 (each) for your vehicle.

Some of the national brand autostores can't get a brake line? They may come in a straight piece, proper fittings on each end. You would have to use a tubing bender for proper bends. Use the old brake line as a pattern for the bends.

Take out all the air and refill the system with brake fluid. Test your brakes prior to driving.

Could be a power brake booster problem. Need to inspect the entire system and not drive the vehicle.

Several possibilities; faulty / clogged flexible brake hoses at the rear calipers, dirty / contaminated brake fluid, damaged rear brake caliper piston, faulty mechanical parking brake at the rear caliper.

your air suspension may have a leak/ sounds like to me you can turn the switch off in the trunk to see if the noise goes away

could be in the abs system its self

Check for power with a test light ground to light sockets then check for ground ,Long piece of wire connected to positive battery terminal
other end to clip 9 tape up if chance of touching ground then probe socket for ground

Check the brake pedal position switch.

I just did almost this very thing this morning! It is most likely one of your break lines that has sprung a leak.
