Breva Rear Brake Pad Switch, this aint right?

[Mayor_of_BBQ]

Hi,
CHanging my rear pads on the 2007 Breva 1100

seems pretty straightforward? But I cannot get the caliper back on!

The piston side sits back and flush to the caliper body
On the 'fixed' (non-piston) side, the pad is in, its tight to the caliper body, but it is just too thick to clear the rotor, as far as I can tell.  I got EBC pad FA181X, which is what Harper's sent me.  I can't imagine its the wrong pad, it seems to fit in caliper perfectly, just stands too proud.

Yet I simply CANNOT get the caliper positioned where the upper bolt will go in, and the pad is fully tight to the disc--so even if it would clear to bolt on, the pad would be running on the disc.


I've never done this bike's brake pads before, I must be missing something completly simple and obvious, but this is driving me nuts??

any suggestions?

It's been a while since l changed mine, but ...

Looking at the second picture, it seems both pads are positioned too close to the non-fixed side. I think this can be corrected by sliding the entire fixed bracket along the pins that are covered by the rubber accordian tubes. (Only one can be seen in the picture.) The bracket moved gradually to its current position to accommodate pad wear. With new pads you need to move it back. I would try using one or two small C-clamps for that, carefully

EDIT: That is, press the gold- and silver painted halves of the caliper together by using C-clamps opposite either end of each rubber-covered pin.

If this doesn't work easily you should separate the two halves and clean up the sliding parts.

Good luck, I had the same with a 2010 Stelvio and EBC. I got nowhere and tried everything I could think of to get it farther opened up. I called EBC and they said "they're supposed to fit but..." I finally used the 1/2 worn-out pad on one side and the new one on the other. worked great. let us know if you figured it out.

OK this might be something....   was looking at the bracket to caliper mounting... I'm thinking the placement of accordion boots indicate this thing is supposed to float or move, but I couldn't move it by hand... will try the c-clamps, thanks!

No can do, my old pads are *down to the metal*...  no exaggeration! Thanks for the response tho!

Wouldn't be the first set of EBC that I've seen that was a real close fit in the caliper. If you are sure the caliper is floating correctly and the pads are still too close, a bit of time with #80 grit will make them fit. Guess EBC is trying to give you as much as they can for your money.

The caliper mount must slide freely on the caliper. (the accordion rubber boots should easily move in and out) It may be rusted and hanging. You should disassemble it, clean and lube the pins that it slides on. If you simply clamp it together, you may cause more issues trying to get it apart. I would pull it apart first and inspect it.

I clean and grease the pins at every service...(20,000 k)
They always look too dry.
Also when fitting new pads, I get a piece of wood about 1” x 1/4”, slide it between the pads and twist it to push the pads apart. Again with lube on the pins and re securing the boots, it’ll fall on...

This was the answer!

The pin was so rusted that the caliper was stick on the mount...  I couldn't figure out why is wasn't 'floating' but thought it either took more force than I could muster with my hands-- or it was just a mount adapter, and it wasnt supposed to float.  Originally I didn't take the caliper off the bracket because I thought it was pinned in it's current position.  Only after I pulled the boots out of the way did I see that there is a guide pin with a wrench flat on it so that it can be disassembled.

Took it apart, used some 1200 grit on the pin and inside the brass tube and coated them liberally with anti-seize.  It floats smooth now and the boots are tightly seated.

Went back together like a dream. Thanks all!

I switched the 01 EV over to EBC HH last year. Wow-what a difference. the one front that works with the rear wasn't worn 1/2 way yet at 90000 miles.

Well found & sorted. The 1TB V7 has a similar mechanism on the rear caliper - semi floats on 2 pins. I was altered to a malfunction when the pads started to seize on the rotor & boil the brake fluid. Found the pins were failing to return because the big boot with the accordion bellow was damaged/mangled (possibly from assembly?) and road grime had accumulated inside the slide. Clean it up & it worked. Was told that the boots were unavailable as spare parts, so would take it apart & clean it more or less regularly.

I've recently found a source for new boots - Powerhouse - seem to be Brembo/Aprilia specialists - so the new boots will be going in next tyre change, if it doesn't jam before that.

There’s evidence that your disc has been scuffing on the mounting bracket as a result of failure to slide..
