Changing rotors and bearings

XRated · 30-08-2005, 02:05 PM

I changed my brake pads the other day (thanks EFFalcon & Karl for the tips). I'm using the new Bendix CT pads on my front slotted rotors - you don't even need to bed these pads in

It's a pity they don't bite hard like the Bendix Ultimates I had on, but I think they warped my rotors slightly and caused too much dust anyway..

Anyway, how do you get the front rotors off? The backs are as simple as one phillips head screw.. And what's the deal with bearings? Are they hard to replace - are special tools need etc??

Cheers

IIRC - take the center cap off, remove the split pins and crown nut and the rotor pretty much falls out.

nah dude, once you take the dust cover off the hub, take out the split pin, undo the retaining nut and pull the bearing out, you will see how it all works. Its a piece of **** really. Just make sure the races go in properly on the new disks and you pack the bearings with grease properly.

Funny how u said the rears were easy, i couldnt get those screws out on my car.

The most important thing to do is pack the bearing properly with grease, and applying the correct pre-load to the bearing (very important).

Exactly what Sox has said, packing the bearings properly with grease is crucial. If your still unsure I'll take a scan of the Gregory's manual and send them to ya tonight. PM me with your email address if you're interested.

undo the to callip-er retaining bolts i think ones a 12 and ones a 13 depending on model. remove caliper and pads and push pistons back. pull off the beariong cap, nok out the split pin and unto the castle nut. pull the rotor off make sure u hold the bearing so it does fall out. once removed it will expose the rear bearing wich just slide off. clean all the components well, make sure the old grease is removed from the bearing, soaking in good ol petrol works well

when its all clean inspect for scorch marks or wear marks, if any of these are visible they need replacing. other wise repack the bearings with High Temp Bearing grease, make sure they packed correctly. light film of grease on the bearing cone and the stub axle is a good idea. too much grease will just melt and be no use. put all back together and correctly preload the bearing. i taught when i started my app to use a 12" cresent for this. tighten the nut right up tight. spin the rotor coupla times then back the nut off spin it again, then to preload the bearing just us the weight of the cresent to do the nut up and thats about right. put split pin back in a bearing cap and thats it done peice of ****, email me if u need to know how to replace bearing and cones

It's a pretty easy job. I found Timmeh's guide really helpful.

Cheers guys, it sounds pretty straightforward. I might do it the next time the pads need changing.. I have used my current ones for only a couple of hundred kms, so if I was to go and get the discs machined, wouldn't I have to get new pads??

Does anyone know how much the rear calliper tool goes for (not a universal one)?
