Carbotech XP10 Brakepad Sensor issues

[jafo1701]

anyone have a problem installing the brakepad sensor with the Carbotech XP10? I can't get the clip into the brake pad, it doesn't seem to fit. The pad itself fits inside the caliper fine, but the clip won't fit into the pad. I tried for a few hours and tried it on the set of pads that weren't on the car yet, doesn't seem to be the right size. I'm wondering if i was sent the wrong pad. I'm running the stoptech street performance right now and the sensor clip rights in. I can see the obvious difference between the stoptechs and Carbotechs as far as where the sensor clips in.

Old thread but wanted to re-use it.

I just bought Carbotech XP10 front and rear pads for my 135i, and ran into same issues. Rear wear sensor clips barely fits, front does not. Decided to tie-wrap the sensor out of the way, and use "visuals" for pad wear detection. I check pad thickness very often, as I track the car.

Love these endurance pads even on the street. No noise so far, decent bite, and rotor deposits are getting cleaned up by cold pads. The pads are slightly smaller than OEM to account for heat expansion, as I can hear a slight clunk noise the first time I apply the brakes and change direction ( back up the car, and apply the brakes for the 1st time, move forward with the car and apply the brakes for the 1st time).

Will get to try the XP10 pads on the track for the 1st time next week. Ive been running on street pads so far, and experienced brake fade (OEM Textar pads), and brake shudder (Cool Carbon pads). Ive installed 0.5mm Titanium Heat shields, and F30 Retrofit Brake Cooling dust shields.

Been using Motul RBF-600 brake fluid for a while, and never experienced soft pedal on the track.

Where is your track event next week ??

ICAR Track in Mirabel Quebec Canada. They host weekly events (Wednesday Lapping Nights from 5-10pm). I also booked 2.5 days driving school @ St Eustache Track April 25,26,27r...

Cool! I don't think the ICAR track in Toronto does any events like that!

Also, I'm thinking of running xp8 for track/street. Just don't know if that's advisable because they are track pads. You said they run fine on the street xp10, so I'm wondering if xp8 will be okay too?

I think the XP8 might be better slightly better for the street, and lighter cars, and last a little less than the XP10 on the track.

I have absolutely no screeching noises so far. I used copper paste on all pad contact points, both surfaces of the Titanium heat shields, and guide pins.

The minor inconveniences with the Carbotech's, if you are willing to accept them are:

#1 - CT XP Pads move around when cold, as they are smaller than street pads. This design allows the XP pads to expand under extreme heat at the track.
(a) So any time you change direction with the car (forward to reverse, or reverse to forward) you will hear a slight clunk sound as the pad slightly moves from top to bottom of the caliper. This will only happen once after you change direction.
(b) when you drive over bumps at slow speeds, you might occasionally hear the brake pad rattle sound.

#2 - CT XP Pads are a little abrasive to the rotors when cold (street use), with a hidden benefit that they will clean deposits off your old rotors. You only will need to bed them just before hitting the track. When you are done at the track and drive them on the street again, you will automatically scrape off the pad transfer layer. Surprisingly, the pads work well on the streets, without any transfer layer or bedding process required, until you hit the track again.

#3 - CT XP Pads are dusty. About the same or a little dirtier than OE street pads.

#4 - CT XP wear sensor cutout is wrong. Not molded properly to hold OE sensor, so you must secure your sensor cable out of the way.

I used Carbotech exclusively on my Mini R53 and tried everything up to the XP8s, which were on it when I sold it. Fantastic track pad. You get used to the squealing with the XP8s. I had my sensors tied up even before I had Carbotechs (around 20k miles) so I didn't really care about the pad. They wore better for me than anything else and were wonderful and the track. I'm happy to hear they are making one for us.

Glad to hear about the extended wear rate ...

Carbotech does make the XP pads (XP8, XP10, XP12, XP20, XP24) for the 128i/135i, but they seem to be a special order item. I waited a month for mine to get produced and shipped to Quebec, Canada. So you must plan ahead ...

The AX6™ is specifically engineered for Autocross applications. A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range of 50°F to 1000°F + (10°C to 537°C+). The advanced compound matrix provides an excellent initial bite, high coefficient of friction at lower temperatures along with very progressive brake modulation and release characteristics. Many drivers use the AX6™ for street driving as well, even though Carbotech™ doesn't recommend street driving with AX6™ due to possible elevated levels of dust and noise. AX6™ is NOT recommended as a race compound in most applications.

Carbotech™ XP8™
A high torque brake compound with a wide operating temperature range of 200°F-1250°F+ (93°C to 676°C+). Carbotech™ XP8™ is the first of our racing compounds. Good initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance and very rotor friendly. Perfect for track day use with any tire and can still be driven safely to and from the track. Carbotech™ does NOT recommended XP8™ as a daily driven street pad due to elevated levels of dust and noise. Carbotech™ XP8™ is a great compound on the front & rear of most open wheel and sports racers.

When Carbotech™ unleashed the XP10™ to the general public it immediately gathered multiple regional, divisional, and national championships. The XP10™ has a very strong initial bite with a coefficient of friction and rotor friendliness unmatched in the industry. Fade resistance is in excess of 1475°F (801°C). XP10™ still maintains the highly praised release, excellent modulation and rotor friendliness that have made all Carbotech™ compounds so successful. Carbotech™ XP10™ is not recommended as a daily-driven street pad due to possible elevated levels of dust and noise.

Carbotech™ XP12™
Another highly successful XP™ series compound with an excellent initial bite, torque and fade resistance over and above the XP10™ compound. XP12™ has temperature range of 250°F to 1850°F+ (121°C to 1010°C+). The XP12™ has that excellent Carbotech™ release and modulation that has made all other Carbotech™ compounds so successful. The XP12™ is more rotor aggressive than XP10™, but compared to the competition the XP12™ is still very rotor friendly. XP12™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.
