Question about 2003 Subaru Baja

2 Answers

Why would the brakes on a 2003 Subaru Baja randomly apply themself at all four rotors causing them to get hot and wheel shimmy? Now the brake petal is getting soft and going to the floor. No fluid lost at all.

Try checking the intake manifold vacuum check valve (to the brake booster).

What causes brake shimmy C2500 1991 5.7L?


Brake shimmy is due to hot spots on the rotor or drum the metal is actually hardened in the spots causing friction differences when the brakes are applied causing front end to shimmy . If you have your rotors turned the hot spots are still present so I have always justr replaced rotors pads all at once shimmy gone .

When brakes applied the steering wheel shakes.


Your disc brake rotors are warped. Solution? Remove the disc brake rotors and have them turned on a brake lathe. Warpage comes from a hot disc brake rotor going through a puddle of water which causes the warpage. If you have a Parking Brake, get in a safe area and when stopping, ONLY apply the parking brake. If the steering wheel stops shaking...there's your problem...warped disc brake rotors.

If your tires were not properly balanced then it will cause that. Also, if your rotors are warped then icould cause this to happen. YOu would also notice it when braking if rotors are warped.

Steering wheel shimmys at speeds 35 and up just changed rotors and pads no play in new wheel bearings doesnt shimmy when i brake though. any help would help greatly thanks


If it shimmies with the brakes applied, it's a rotor problem....but like you say, it shimmies just at a certain speed with no brakes applied, check tires for out-of-roundness. If they look ok, you are looking at a balance problem with the tires.

Front brake shimmy


I would try replacing the rotors altogether.If after resurfacing them your getting .010 runout on them in a few days, those rotors are getting soft.
Also, check the rotor mating surfaces, ie, where the rotor touches the hub when installed, and make sure it is clean and smooth. Any rust or brake dust buildup on the hub will prevent the rotor from sitting flush to the hub. I would also recommend replacing the brake pads, if you do the rotors, as the pads could have worn unevenly due to the rotors being warped.

Removing front rotor


When you take off the wheel, you then need to take off the caliper witch is held on by 2 bolts, (may require a special socket) after removing caliper carefully let it hang by brake line. Then the rotor should slide right off.

I have a shimmy in mySteering wheel not all the time it comes on randomly.


In absence of more information, this is usually an symptom of warped brake rotors. A rotor can build up enough heat in a hard stop to be bendable especially with the high hydrolic pressure a brake pad can bring to bear. Simply, If you keep the brake pedal depressed hard after a hard/long stop it can warp the rotor. (NOTE: at a hard stop, as soon as possible let the car creep forward a few inches at a time so the brake pad won't be on any one spot too long, plus keep light brake pressure --only enough to keep the car from rolling). The warped rotor causes the brake pad and caliper to float too far from the rotor and you won't feel the shimmy until you apply brakes. Under brake pedal pressure each time the wheel rotates under brake pressure the rotor and caliper will rapidly vibrate a few millimeters to each side giving the sensation of a shimmy in the sterring wheel. Most of the time this can be corrected by having the rotors resurfaced( aka Turned)

Out of balance or out of round tires can also cause a shimmy but should occur at a given speed range. Warpped rotor shimmy occurs during deceleration.
