My baby has new front rotors...

Falco80 · 05-08-08, 09:23 PM

Bolted up some new slotted front rotors yesterday to replace the originals. Replaced the pads and front wheel bearings too while i was at it. The wheel bearings took me a while to do, as it was my first time, but it all worked out ok. I love the massive 4-piston calipers on the 80! It's great knowing i'll be able to stop in a hurry now if needed.

SOCALFJ · 05-08-08, 09:26 PM

Very nice! What brand did you go with?

FredTJ · 05-08-08, 09:28 PM

Just make sure that you bed the new pads/rotors in so that you don't fubar 'em up.
One of the most common mistakes made when doing brakes, failure to properly bed them in.

They are DBA (Disc Brakes Australia) rotors. Picked them up for a good price at a local auto parts store when they were having a sale.

That's right Fred, I'm taking it easy don't worry. I don't drive it like a race car anyway.

IdahoDoug · 05-08-08, 09:39 PM

Me thinks you're missing the point, Falco. You DON'T want to take it easy - you want to properly bed them in with several hard stops to ramp them up to a very hot temperature right after installing. Doing/not doing this determines the future of the brakes effectiveness.

Yup, "taking it easy" is about the best way to pooch 'em up.

Yep, i'm aware of the need to bed the pads in. I've been out today and did several heavy stops and got everything nice and hot. I drove steadily yesterday purely because of the new wheel bearings i put in and just wanted to make sure they were rolling smoothly, which they are.

Mudshack · 05-09-08, 02:54 PM

So even if you go with stock rotors, you still want to do a series of "hot" stops after the install?

You always need to bed in new rotors and pads.
A series of "hot" stops is not the correct way to bed them in.

Here is the process I used last year on the 80 and this year on the LX...80 got new OEM rotors and OEM 80 series pads and the LX got new OEM rotors and 100 series pads. FWIW they both stop dramatically better than before and I am very satisfied with the OEM setup.

Seems to have worked just fine and if done late at night, it usually isn't something that will get you any strange looks

BRAKE PAD BEDDING IN PROCEDURE

Mudshack · 05-09-08, 04:25 PM

Ahhhh...I just got done reading much on the bedding. I am doing new rotors in the rear, and new pads all around. So I will take it easy on the bedding in.

Just FYI but since you are doing all new pads you're ok...But for those only replacing the rear pads:

"This bedding process is only suitable for the front axle - not the rear. This is due to the brake force distribution of front and rear axles. In order to reach 300°C (527°F) on the rear pads you would have to drive several miles with dragging brakes. However, in that time the front brakes will be glowing red, overheating and thus destroying the front brakes."

LC80Ducati996 · 05-09-08, 09:58 PM

Just did my fronts..

Just ran with raybestos replacement rotors (~$75) and performance friction pads.

Going to replace the rears and overhaul the parking brake system as well later this month..

topend yobbo · 05-09-08, 10:51 PM

Did you use the 100 series front pads?
Does the old girl stop better now?

Oh, this is just perfect.

So I just put brand new OEM rotors and 100 series pads on the wife's LX. Been driving it the last week to make sure everything is working properly. I have been driving it gingerly for the most part, but did a couple of hard stops the first night I put it back on the road. Maybe three stops from about 50mph down to 15mph, but did not drag the brakes as described in the link provided by corsair23. The brakes seem to be stopping much more positively than with the old set up. Is it too late for me to do a break in on the new pads/rotors? I've put about 150 miles on them thus far. Sorry for the hijack, but I felt it was pertinent.

Thanks.

IdahoDoug · 05-10-08, 10:03 AM

No, you can still do a bedding procedure. In fact, it will work at any time to revive cludged up brakes, but works best on new ones. I usually get to do a rebed about once a summer when some moron pulls out in front of us while we're towing 3 tons of boat. Usually an elderly couple from Canada*

Nah mate, i used 80 pads. I'm going to give the 105's a go next time though. The 80 stops a lot better than before, but thats mainly cause the old pads were very worn and just farked....

Give the EBC 7000 series a go.
They are second to none (bedded in correctly) and will make the vehicle stand on it's nose.

A lot of pads were tested about 1 1/2 years ago (blind test for those actually putting the pads on their vehicles) and the EBC 7000 series were the best, hands down, over all the other brands tested.
I run them and they're simply great.

Fred

theyis · 05-11-08, 11:13 PM

So what do you do to bed the rear pads in if you are replacing all four sets at the same time? I just bought new rotors/pads for all four and will be installing shortly.

Thanks,
Kyon

Brian894X4 · 05-12-08, 12:45 AM

Are there any differences between the 80 and 105 brakes? Brake size, booster, etc?

Just curious.

Pogue · 05-12-08, 04:59 AM

Doug, is there a link to the procedure to properly bed a Canadian? (preferably not elderly)

Ummm, am I missing something???

Those posts are why I asked the question in the first place.

This bedding process is only suitable for the front axle - not the rear.

I, too, must be missing something, as both posts 11 and 13 say the same thing: that bedding process does not work for rear brakes.

corsair23 · 05-12-08, 10:42 PM

You aren't missing anything

As I understand it you CAN'T bed in the rear brake pads like you do the fronts...Basically you don't worry about trying to bed them in. Trying to do so would destroy your front rotors and pads...
