I don't have them installed yet, so I can't give you much of a first hand review. :(
No, I haven't received mine yet. I just got home from work and found my Independent 4X steel brakeline kit delivered to the doorstep; but, still waiting for rotors and PBR/AXXIS brake pads.Quote:

As far as the issues with stones....I live on a dirt road with lots of stones of assorted sizes....all the way down to the granular stones you find in a handful of beach sand. If this IS an issue...I'll report back to you guys about it. Thats kind of why I didn't mind buying the Autozone rear rotors now because they'll be good to have (along with my original front rotors) if I encounter any problems with stones lodging in the holes of the R1Concepts.
The holes aren't bad, and are quality - I guess I was expecting them to be satin smooth but seeing as they're machined I was probably being unreasonable and picky...
So far so good with the rotors. Initially they seem to provide a little more 'bite' upon braking - however, I'm not sure if it's the rotors or the new Independent 4X brake line kit? Either way, they seem to work/perform good - but only more time will really tell...
-biju.
Well...the good news is that I got my R1 Concepts drilled/slotted rotors delivered today...the bad news is they sent me 4 front rotors instead of 2 front & 2 rear. I emailed them tonight so we'll see how good their customer service is.
they look to be well made...I had no issues with the drilled holes or slots...all seem to be machined nice & cleanly. They were packaged well too.
I'm going to order mine soon. Let me know how it works out.

So here I am 6 months later and getting a grinding noise when I brake, I was replacing the front shocks with Ranchos and told them to check out the brakes and discs. "You've got about a thousand mile left on the front shoks and the discs are OK.
But on the way back from the shop the grinding got that little bit more noticable, I ordered pads that night. when I took them to a different shop to get them fixed while I was at work,(pouring rain no garage,middle of winter, would you?)
They rang back and said they wouldn't put the pads on as I desperatley needed discs. So the Golden Rule is if you feel it ain't right it more than likely isn't.

LOL, interesting thread. I'm at 133K miles on the original rotors and will have them turned (if needed) as I do need pads for the front, which will be the Axxis pads since stopping is kinda important to me :p and they've proven themselves in AutoX and RallyX circles here.
I am in the market soon, any updates on the R1 product?
i'm curious, as well. although more interested on the pads.
i still haven't been able to find an answer to -
what compound are the OEM pads made up of? (semi metallic, ceramic etc?)
the auto parts stores keep telling me OEM's are ceramic. don't want to try the wrong material on stock rotors.
-jose
An update: After emailing them, they responded with an automatic email saying to expect 3 day wait (business day) before a response to my email; which turned out to be about right...they responded with a request to resolve over the phone (no 1-800 # though)....so after talking to them a couple of minutes (they were nice about it and apologetic), they emailed me a return shipping UPS label to send back 2 of the front rotors and promised to ship out the correct rear rotors after receiving them. I'll let you know how it turns out.Quote:

I've had issues with other vehicles I've owned pertaining to the disc brakes too...but in those cases the vehicle would pull to one side or the other indicating a problem that could be quickly addressed. With my VX, because it is both inner pads sticking, it doesn't pull to either side and gives virtually no warning because the wear indicators are on the opposite (outboard) pads.Quote:

My VX rear rotors show excellent wear on the outer pads and were used up on the inner pads...down to the rivets..which is what I started to hear screeching. :eek:
If there is a bright side...alot of my previous vehicles had caliper piston malfunctions too...where the piston would get stuck either intitially before engaging the pad resulting in unbalanced braking or during braking where it would'nt release resulting in pulling to one side. My VX has not exhibited any of these issues.
Well, just to let you guys know, they came through with sending me the correct rear rotors in exchange for the 2 front rotors I didn't need (they sent me 4 fronts instead of 2 frnt + 2 rears). Now all I need is for winter to go away!Quote:

Hopefully they will ship soon! I can't wait to get these on so I can start driving like a maniac again! (I have been taking it easy cause I know my pads are worn down pretty bad right now).
Bart
not too sure I'd buy my R1's over again if given the chance...(but maybe because I have limited to NO experience with how drilled/slotted rotors *should* perform...??)
the face (surface) on my rotors are BROWN? - and the slots get all filled up with pad gunk constantly. (doesn't this defeat the purpose of the slots? ha.)
Is this supposed to be? I always see other rides with drilled/slotted rotors and their surfaces are gleaming silver/clean - w/ no build up in the holes or slots...
I dunno. I'm picky tho. maybe this phenomena will subside over time, and is only because they're still new.
-biju.
Well, what about the braking performance? I mean, I really hope this wasn't a bad choice. I need brakes pretty bad now, but if these are going to be bad for my VX.... :eek:
So you are saying they are like rusted? Or just dirty? I wonder if I should try to get them exchanged for regular rotors (non-drilled and slotted)??? Do you think that would be better?
:confused: Bart

performace on the R1's are fine so far, but just concerned about what I'm seeing... My hope is this is just stuff happening due to a 'break in' period of new pads/rotors, etc.... and crossing my fingers that what I'm seeing isn't the begining of the end. ha.
again - right *now* - they work great.
-biju.
Yeah, my hope is for performance and longevity. You can't really see my rotors through the Chambers, so looks isn't really a concern. I just want good, long lasting stopping power.
I don't want to have to change my brakes again before Moab!
Hopefully, R1 will chime in on this thread again and let us know what's going on in your case.

Basically, I will know more once the plans come together.

your wife WILL be missing out if she doesn't go! glad to hear you're making it tho.
back to the rotors... I think you'll be fine with R1's product. I think I'll be fine with R1's product... I'm just nervous about the brown burning look/effect and the clogged slots. Again, might just be a break-in thing...
-biju.
Yeah, well, her main reason for NOT wanting to go is that she does not want to camp. I want to camp in the Great Basic National Park on the way, to break up the 12 hour drive, and camp in Moab. She however, does not like camping (probably because I start to reek after only about 12 hours without a shower, especially in the summer).
So we'll see. I'll keep working on her. It doesn't help that our wedding anniversary is on May 13th. That may thwart my Moab plans in the end...
Only time will tell.

Anyways, Jolly Roger VX'er, I'm glad to hear that you received your parts and that the representative helped you.
If you guys have any more questions, feel free to ask me. thanks
OK, so I got my R1 Brakes and Rotors installed on Saturday, as well as the front bearings repacked. So far so good. The brakes seem to function good, although I do see the brown tinge on the rotors that Biju was talking about.
R1: Can you explain/comment on this please? Just to give all of us anal VXers some peace of mind on this?
Thanks - Bart
HEHEHEHE :pQuote:

nfpgasmask, good to hear they're working for you. If you experience the same problems as Biju, feel free to let me know. I don't want this to be of a big concern to other buyers. Thanks
Cheers!
I'll see what I can do tonight with pix...
Thanks r1.
-biju.
NP, anything to help the VXhers!
I can try to snap some shots too, as mine are brown already as well. But like you said, its probably nothing to worry about....but...
Thanks - Bart

OK, even with the sun shining today, it was difficult to get a good quality pic of the rotors through my Chambers. There isn't much room to see through.
This is the pic that came out the best:
http://www.vehicross.info/gallery/da...ium/rotors.jpg
As you can kinda see, the surface of the rotor is clearly not silver anymore, but now has a brownish tinge to it.
Other than that, these brakes and rotors seem to perform just fine. I have purposefully tried braking hard on a few down hill stops to see how well they bite, and they do seem to need a little extra pressure, but otherwise work just fine.
So, R1, any ideas what this brown discoloration is from? I'm sure its nothing to really worry about, but if you could shed some light that would be excellent...
Thanks - Bart
Biju,
Is there any update on the rotors? I was thinking of replacing pads and rotors when I got under the VX to repack the front bearings (might also paint the calipers too). Are they working fine? Has the browning gone away? What's your overall opinion?
Inquiring minds want to know.
Hopefully Beej will reply also.
I have had the R1 Rotors and pads on now for about 2 weeks. The browning is still there, and we have had no response from R1 regarding this. So, I don't know what to say about that.
As for performance, I'm on the fence. It seems like with everyday normal driving on FLAT surfaces, the brakes work fine. But just yesterday, I was driving through the mountains and one a winding road going downhill, the guy in front of me slowed down to make a turn with no signal real fast. I started braking and the brakes were not gripping very good on the downhill. I actually got a little scared for a second. So, I don't know, I mean, is it the weight of the VX that was causing this? Or brakes that don't bite as hard as they should? Or is it an anti-lock issue? If I am going down a moderatly steep hill at say 30mph, and I JAM HARD on my brakes, should they lock up my wheels? I didn't like the feeling that my brakes were not working very well. Its almost like I need to STAND on the pedal to make the brakes grip as hard as I felt they should. Could it also just be that the brakes are new and need a little more time to break in?

i mean, they were only a couple hundo for the set - so i can't complain. great looks, equal if not slightly better performance than the oem's (but could be due to new pads).
the browning? it seems to be gradually getting less and less noticeable - although still slightly there. i have a feeling it will continue to decrease (*crossing fingers*).
because my garage is down to one vx i find that I'm braking much more often these days, being extra careful/mindful of traffic around me. brakes work just fine and feel really solid - i'm confident.
would i buy them again with the same budget? >> yes.
bart: i'm not a gear head/mechanic - but maybe an adjustment is in order? - or possibly low brake fluid?? :confused: :confused: ... just a thought.
-biju.
Well, like I said, under normal conditions, they seem fine. It was just that downhill experience I had yesterday that kinda freaked me out.
When you get your brakes and rotors changed, don't they have to bleed and refill your master cylinder?
Bart

That browning would concern me a little since steel turns colors when being heat treated/tempered. Are you getting any colors besides brown in there, like purples or blues? I have never had disc brakes turn brown......
I know what you mean about other colors, like when you take a grinder to a fresh piece of steel. No, it just looks like a brownish film. Not quite rust colored, more somewhere between a "burnt umber" and a "raw sienna".

Bart
PS - When the fark am I going to see your VX on the road??? :)
