Brake Rotor Replacement

Hey Guys,

Planning on doing the brake rotors along with brake pads at some point in a few months.

Can anyone who has done their rotors before let me know if you have to drain brake fluid in some way? Most cars i've seen have flexi hoses for brake line so you can get some movement of the caliper to allow for the rotor to come off without needing to drain fluid etc.

On a quick look at the 120's setup it seems like they are solid connections with little or no movement. The rears maybe you could unbolt the solid connection and get just enough flex but the front ones look too short to move. I could be wrong but that's how it seems.

Any thoughts on how to approach this would be appreciated and even better if someone had photos!

Wes

No you don't have to disconnect the hoses if you're just changing pads and rotors, meaning no need to bleed them.

It helps to have a couple butchers hooks on hand to hang the caliper on once it's unbolted rather than taking it off then seeing what's within arm's length...

If you're going to change the rotors and pads, I recon flush the fluid as well. When you push the pistons back, you'll be sending the old fluid back up the line and possibly into the master cylinder. The fluid in the calipers is much more worn and dirty than what you see in the reservoir. If you've bled brakes before you'll notice the fluid that comes out with the first few pumps is much dirtier than what comes out a few pumps later as the cleaner fluid makes its way from the reservoir down the line.

So unless I missed it did someone mention why choose DBA T3 over T2 rotors? From their website all I can see as a difference is T3 are for HEAVY towing applications and Show Cars.
So aside from that I can assume T2s will be more than adequate if you are not long term towing something big or presenting your 4wd at Car Shows.

Which bolts do you need to undo to release the caliper from the disk, does one need a pneumatic gun for the job?

You shouldn't need a rattle gun but a breaker bar will help crack them initially. (Might be a typo but the caliper is not bolted to the disc)

As far as brake bleeds go i clamped my flexi house (Using the right brake clamp tool) and cracked the bleed nipple on the caliper i was pushing the piston back into to get the crap fluid out. Then a full bleed at the end.

In the end i went with the T3 Discs and am really happy with them.
