Hi guys, has anybody replaced their rear discs and pads ? How easy is it to get the wheel bearings out of the discs ?
how long did it take you ?
Thanks for the help.
-
The rear discs on mk4s don't house the bearings, they have a separate hub.
-
Thanks for that mate, it makes the job nice and easy. It was my understanding that they were a press fit in the hub.
-
It's just winding the pistons back into the calipers that is a pain in the arse to do - well worthwhile buying or borrowing the correct tool!
-
or if there's two of you, it can be done with a g-clamp and pair of grips.. thats what i did at the weekend anyway 8)
-
i use the g clamp method, its not too bad, dunno why you need a pair of grips?
remember to undo the bleed screw and let the fluid out through the nipple rather than force it back through the system. Apparently i've been told this screws the pump up and it also warns against it in my haynes manual.
have a nice day

Just out of interest, what milage did you get out of your rear discs/pads?
I had my all my brakes done (front discs, 2nd set of pads, discs and pads on the back) at 56k miles.

Now on the 2nd set of rear pads at 65k (remember how low they were at AmD ? just changed them on Saturday? ;D ), fronts no clue, still going strong.. i assume the previous owner had them changed.

As for the grips, thats so you can rotate the piston at the same time as pushing ( a makeshift wind back tool in effect, thats why your piston has two notches in it ), that way you don't need to release any fluid through the bleed nipple, just leave the top off the reservoir. This not only eliminates possible air locks, because lets face it bleeding the brakes is a pain in the arse, it's also the recommended way of doing it.

Never use a g-clamp on its own with rear calipers, you could damage the internal handbrake mechanism.

oh right that makes sense. the cramp i use is fixed so as you wind it it spins the piston round anyway. surely if you push the piston in it will still force fluid the wrong way through the abs pump?
