My break lights wont work on my 2003 suzuki aerio

First of all, if the engine turns over, you DON'T need a starter or an ignition switch. Don't fall into the 'let's try replacing this' method of car repair! It is costly and never works.

First replace the cap cap, it is part of the pressurized fuel system and may be the answer to all the issues. $20 from Walmart, or $15 from Napa Auto Parts.

Then connect a code reader and find why that Engine Light comes on. Your vehicle has a computer that records everything that is wrong with it. A cheap code reader gives you the basics, a $5,000 scan tool computer tells you everything, historically and in real time as the vehicle is starting of being driven.

The other thing to check is that the battery is good. Interstate will test for you for free in the parking lot and only takes 2 minutes including the printout. I think AutoZone and Napa also does it.

is the break pedal hard as well maybe a bad brake booster

Hi, Just spray some DW40 in the ignition switch. Then put the key in and turn and wiggle it. If you have steering lock work it some more till it does.
Good luck.

Sounds like you first need to go to Auto Zone and have them scan the computer for the check engine light code and find out what is going on with that..it is probably a misfire code, they will print out the code and the cure, may need a good tune with wires.
As far as the wheel soot/?
You may have a leaking axle seal/worn brake pads/frozen,leaking brake line or disc caliper(check the brake fluid level in the master cylinder to confirm a brake fluid leak)

PARKING BRAKE HAS TO ADJUSTED IF OUT OF ADJUSTMENT.

omg this car is pain to change timing chain it takes me 9 hour to do it with one 30 min break,if you dont have a experience changing timing chain before,do your self a favor let the pro do it.trust me.

there is a cable underneath the car with a turnbuckle style of adjustment on it.IF your car has drum brakes on the rear = adjust those first then try the e brake

check your fuses, if thats not it, change the bulbs. good luck

Yes the phillips head screws have to be removed, on some models there are two more holes in the face of the drum to insert threaded bolts to remove the drum, simply thread the bolts in to remove the drum.
