I have an 03 Camry as well...
I'll suppose you are starting with the car supported and the front wheels off...
Remove the brake caliper by removing the 2 bolts behind the rotor securing the caliper to the caliper bracket. Swing the caliper up and off of the rotor and secure out of the way...do NOT let the caliper hang by the brake hose.
The brake rotor should just slip straight out from the hub...if not use a hammer to tap around the outer edge to release the rust between the hub and the rotor...
The answer and dimensions are stamped in the stock brake rotor of your vehicle.
nb,
What is the minimum rotor thickness of the front and rear brake rotors on an '03 VW Jetta TDI?
The 2003 Toyota Camry has 41.6 in. of front leg room.
The 2003 Toyota Camry has 39.2 in. of front head room.
The 2003 Toyota Camry has 57.5 in. of front shoulder room.
The 2003 Toyota Camry has 54.4 in. of front hip room.
i need knows wtah size is rear and front brake discs.
The brake rotor thickness for your 2003 Mitsubishi Eclipse, is 0.75. The rotor should not be used if the thickness is less than this.
The front track of the 2003 Toyota Camry is 5 ft. 0.8 in. (60.8 in.).
To remove the rear rotors from a 2003 Toyota Camry, first, ensure the vehicle is safely elevated and supported on jack stands. Remove the rear wheel and brake caliper by unbolting it from the mounting bracket, then slide the caliper off the rotor. Next, remove the caliper bracket by unbolting it, and then you can slide the rotor off the hub. If the rotor is stuck, gently tap it with a hammer to loosen it.
Your front breaking pads are needed to be repalced, you might have to replace rotors.
