2015 Can Am Spyder RT rear brake piston fully extended outward against the bracket housing .
Had mistakenly engaged parking brake with the brake pads removed.
Now unable to turn (CW) and press the piston back into the hydraulic portion of the housing.
Suggestions or comments are welcome.
Thank you.

My thoughts are.
If you have not removed it completely yet, do that. Then while its off the bike give it a workxburger clean up with cleaner and a toothbrush. Lube the pistons , yadi ya , plenty on the net if you dont know how. Then reset the piston back. Refit with new pads and bleed the lines.

Hi Gerald,
You mean disconnect the brake fluid line and completely remove the rear brake assemble?
If so, I thought of that, however was hoping there was a spanner wrench of sorts to fit into the two piston holes to enable turning the piston CW (inward) without disconnecting the hydraulic lines.
How does one go about bleeding the rear brake line?
Would the front brake assembly need bleeding also?
Thanks for the input, much appreciated.

Gidday Tom.

There is a service tool for that piston I believe. Some use a pair of needle nose pliers and push and turn.
There is info videos online if you need to watch it.

The piston bit is about 5 minutes in.

You mean disconnect the brake fluid line and completely remove the rear brake assemble?
If that wont work for you, well yes, disconnect the line and work on it on the bench.

u-tube is your friend. Description is long and convoluted.

Yeah why not, its one system. You start with the one at the back farthest from your brake fluid reservoir.


Thanks for the input, much appreciated.

No worries. Have fun.

Judging from the questions you are asking, you should NOT have tackled this project in the first place.

An ABS brake system with integrated stability control, like is on a Spyder, it considerably more complicated than conventional brakes.

A BUDS computer connection likely will be required to finish the job right.......and without working brakes, you might have to have it towed to a shop.

Tom If you need any further advice or have more questions well I am happy to help where I can.
No question is a dumb one.

Why is a BUDS computer connection likely to be required?

Thanks for the input.

No worries.

That is what the forums are all about. Helping blokes out.


Sadly some seem to forget that.

 

[Gerald Mac]

Why is a BUDS computer connection likely to be required?

The bike computer throws a code sometimes. Its part of the nanny setup.
Like if you were rotate the rear wheel and not the front wheels it dosnt like it.
Like for instance doing a belt alignment running it with its ass in the air and in gear ideling in 1st gear. With the front wheels firmly chocked.
A short few meters ride and it clears without a buds connection.

Dont worry too much until it happens.

Watch a few videos on bleeding the brakes. You will soon sort the Wheat from the Chaff.

Why is a BUDS computer connection likely to be required?

Because each individual wheel is actually controlled by an electric "valve" and they are not driven directly by the master cylinder like in a conventional brake setup.
Or to be more accurate I guess.......each individual wheel can have the braking force reduced electrically for the ABS and Stability Control functions.

I am not sure exactly why a computer connection is required but I have seen that mentioned over and over.
It sometimes is said that you need the computer connection to do a proper bleed.
Also if your manually operating the brakes causes a brake fault alarm, you would need the computer connection to clear that.

Well Easy Rider, in my humble opinion, it is better to try and fail, than not to try at all.
Trying and sometimes failing is how one learns.

Gerald,
Well, I'm having difficulty removing the brake fluid line from the hydraulic actuator.
It's a 12mm fitting which is very tight. I'm unable to loosen it so far.
Maybe there is loctite on the threads?
I'm being careful not to round off the flats on the fitting.
Suggestions are appreciated.
Thanks,
Tom

 

[Gerald Mac]

OK. So Im assuming you have watched the videos and stuff and guessing you had no luck re-seating ( push and turn ) the piston?

Whats a "hydraulic actuator"? Rear brake assembly? I would re-mount the brake assembly before I attempted to remove the brake fluid line.

Leftie loosie - righty tighty for most threads.

Just made a pot of coffee, waiting out.

 

[Gerald Mac]

Ok . Coffee is consumed.

Got a job to do as some rain is on the way and want to get this sorted.

There are 3 stacks like this awaiting my attention.

Will check in about Brown O'clock this arvo I guess. Be ready for it after that light warm up work out.

 

[SpyderTom]

Well, I was able to loosen and remove the brake fluid line from the Rear Brake Assembly, thus enabling removal of the Assembly from the bike.
With the Assembly mounted in a vise, I was then able to rotate the piston CW with a pair of needle nose pliers to the full "IN" position.
Now, I suspect its best to install the new brake pads into the Assembly before mounting it back on the Spyder?
What do you think?
Thanks,
Tom

Well I got 1 load in before the rain arrived so the covers are on again.

I guess you have gone ahead and replaced the pads and remounted the caliper by now.

I was a little concerned with the piston thing, hoping it was not damaged but I see you got it back.

This may be of interest to ya.

Brake Fluid Flush

I recently purchased a 2017 Spyder RT Ltd with only 5912 miles on it. The manual advises to flush the brake fluid each 2 years, so to be safe I assume it has not been done. A local dealer service uses a computer assisted method that their book says takes 6.8 hours and they get $166 per hour for...

Well, one does not know their limitations until one tries first.
