Removing the front brake rotor on a 1998 Mazda Protege
I went to put winter tires on the car and snapped off three studs. Trying to get the brake rotor off to have a look at the wheel hub and get the studs replaced.
Any suggestions? Do I have to remove the big center nut to get the rotor off?

Re: Removing the front brake rotor on a 1998 Mazda...
You do not have to remove the big center nut. You might have to tap on it with a hammer to get it off. If there is anything solid near it to pry against (don't pry against the dust shield) try that too. If none of this helps you can try heating it near the center. You should be able to get it off without heating it but it is possible that that is what you will have to do.

What you have sounds like warped rotors. They will cause a pulse or vibration in the brake pedal. This can be caused by:
1. Rotors worn too thin. 2. Riding the brakes and/or constant hard braking 3. Sticking calipers (usually also have a pull to left or right) 4. Worn or out of adjustment rear brakes causing excessive load on front brakes.
Nothing. The rotor is held on by being sandwiched between the wheel and the hub. You slide it (the brake rotor) over the studs and mount the caliper over the rotor. Then fasten the caliper to its attach points. When you mount the tire/wheel and tighten the lugnuts this prevents the rotor from coming off. Get yourself to the local library, and checkout the automotive repair manual for your make and model of car. Run through the steps for removing/replacing the brake rotor. Verify you did all the steps correctly!! Good luck.
It sounds like your rear brake pads are frozen to the rotor, or a small amount of rust is causing them to stick. Put all the tires back on and try to drive a few feet, that usually pops the pads off the rotors.
It is not recommended to drive it like that. It's not too bad to replace but it depends on your level of mechanical skill, You need to remove the brake caliper and disc and then you can simply knock the remains of the broken stud out with a hammer and punch, To fit the new one insert the stud and then put a large nut over the thread, then fit the lug nut and tighten it to pull the stud into the hub, then simply remove the lug nut and put it all back together.
The studs are in the hub behind the rotor and it has to be removed because the studs have to be driven out with a hammer (and punch when broken) and driven back in. When you buy the new studs, you'll see what I mean.

Remove brake master cylinder filler cap (2162). Check fluid level in brake master cylinder reservoir (2K478). Remove brake fluid until brake master cylinder reservoir is half full. Discard removed fluid.
Raise vehicle on hoist. Refer to Section 00-02 .
Remove wheel and tire assembly from front disc brake rotor mounting face. Use care to avoid damage or interference with disc brake caliper (2B120), front disc brake rotor shield (2K004) or front wheel knuckle (3K185).
Remove rear brake pin retainers (2N386). ( I think it is a T 40 torx bit you need)
NOTE: It is not necessary to disconnect hydraulic connections.
Lift disc brake caliper from front disc brake caliper anchor plate (2B292) and front disc brake rotor (1125). Do not pry directly against metal caliper piston or damage will occur.
Position disc brake caliper out of the way and support with wire to avoid damaging the disc brake caliper and front brake hose (2078).
Remove outer brake shoe and lining (2001) assembly from front disc brake caliper anchor plate.
Remove inner brake shoe and lining assembly.
Position lug bolt (1107) to clear front wheel knuckle (3K185).
Remove lug bolt from wheel hub (1104).
Install lug bolt into wheel hub.
Using a lug nut (1012), seat wheel hub bolt into wheel hub.
Install front disc brake rotor and disc brake caliper. Refer to Section 06-03 .
Install wheel and tire assembly. Tighten lug nut to 115-142Nm (85-104 lb-ft).
Sounds like it is your brake light switch which is located on the brake pedal itself. Should cost around $20 at autozone and is pretty easy to change out yourself. Thanks for rating my response and for using FixYa!
