Default Brake rotors easy??

How easy is it to replace front brake rotors on 98 GS300? Do I need special tool or do they pop off?

Thanks peeps.

For my car (98 GS400), the rotors fell right off, no problem. I've had pretty good luck with removing rotors on my other cars too, just lucky I guess. For a friend of mine who has a 99 GS400, he had to use a pry bar with a long cheater pipe to get the leverage to dislodge the rotors. Depends on the corrosion, probably.

Before hand, even a day or two, spray the caliper bolts with wd-40 or the like. Also, take the wheel off, and spray were the wheel stud protrudes from the holes in the rotor, and hopefully it seeps in there.

Do all the above, then use hedge hammer and hammer the edge around the rotor. Dont hold back the swing. It will loosen the corrosion and the rotor should drop right off

I believe the rotors have 8mm x 1.25 screw holes to help pull them off the hub. I prefer to use it rather than a sledgehammer if the rotors are stuck on tight.

Exactly, we aren't cavemen, you risk damaging the rotor. Just use the bolt method as that's how it was designed.

I have learn new thing today. I saw the hole on the rotor too, but didn't know what it was for. Would love to know how to use it to remove rusted rotor, if someone can demonstrate or youtube.

I also found something on youtube
for the cylinder to remove the rusted rotor. I am sure will use that method next time.

I must be lucky. Of the million cars I've done this for, I've never had a front rotor not 'hang' once I removed the caliper and bracket...

You just get a bolt that fits the threads, I think it was mentioned in an above post and put it in that hole and tighten until the rotor pops loose, it's that simple.

Pulled this image off google.. but it's the same thing for our cars. I typically use one screw and go back and forth between the holes but two screws would be faster.

You don't have to do this, but whenever I change brakes, I always put a bit of anti-seize or something between the hub and the back of the new rotor. Here in Buffalo everything rusts to hell, and doing this has made brake changes ect. much easier.

+1 on this. Please remember to go back and fourth between the 2 screws. If you just crank on one too long your probably gonna tweak something.
