I took my front wheel off today and saw the brakes properly for the first time. I was concerned when I noticed that the brake disc has screws in only two out of four holes. (The unfilled holes are circled in red). Is this normal? safe?

Ron

Graham I doubt that's a problem since the rotor is not going anywhere once the wheel is bolted on.

Graham,

There is nothing to worry about. This is normal. As Ron stated, even if you were missing the two screws, once the wheel is on, it is all secure...

Boy you have had a busy time recently with your DIY projects....

Agreed... Some cars don't even have screws all together. It's probably more to keep the rotor on while you are (dis)assembling the rotor.

When the wheel is back on, those 2 extra tiny screws are going to do squat ( in terms of keeping the rotor on ).

Thanks guys. Better to be safe than sorry.

That's true. I am 'between jobs' at the moment, which has turned the tables completely with respect to available time and money. I am enjoying the DIYing while it lasts

Graham you should come over to my house to help me do all the projects I have to do in the next couple weeks - pull out the roll bar for good and get it ready to ship to the new owner, remove the AC from the 964 and get the seats redone, add a fire suppression system to the 964, brakes on the 964, install the hot lap...

Way too much to do... While it pays the bills, the day job just gets in the way of the fun car projects.

Funny, I've heard that before. Nah... can't be true...

graham_mitchell

Sounds like a lot of fun but you are aware that I live a few thousand miles away, right?

Hi Graham,

I don't see any countersinking on those other two screw holes so they are probably not meant to be used.

Cheers,

Are the holes threaded? If so, they are meant to help you remove the rotor from the hub (if need be) by screwing bolts into the holes, thereby forcing the rotor away from the hub. This is the preferred method over manhandling the rotor off, or "malletizing" it off. Much easier, and rotors do get stuck on the hubs sometimes.

Graham: Yes, I know you live close to 2500 miles away. It's about an 11 hour flight. I only live about 25 miles from (viper) Bob, so you could get a lot of DIY work done during a visit! We would even serve good beer in your honor.

I think those screws are to back the rotor off the axle if it gets frozen on there? am I wrong here??

Coleman,.

Yep, those holes are there to remove a frozen rotor by screwing in a bolt and "walking" the rotor off.
