Default What Might Cause this Change in Front Brake Behavior

Over the last few days, I changed both tires on my 2012 XCT. I did not bleed the brakes and I did NOT replace the brake fluid, pads, or rotors. While the wheels were off the bike, I did squeeze the brake levers/pedal a bit to push the pistons out on all three calipers a little and I then cleaned the portions of the pistons I could access. I used a large screwdriver and a small crowbar to push the pads out and, hence, the pistons back in in order to get enough space between the pads to fit the rotors when I reinstalled the wheels.

I test road the bike today after the work was done and the front brake behavior has changed. It was never spongy and is still not. However, the distance I have to pull the front brake lever before I cannot pull it any further has substantially decreased. Now, I don't have to pull the front brake lever very far before it reaches its full braking ability - maybe 3/4 inch. This is really weird since prior to this work, I had to pull it further - maybe 1.5 inches. Any ideas on what might cause this would be appreciated.

G'day,

Released some air pocket when you pushed calipers out and by pushing it back in allowed it to get into the line and float up.

When was last time you changed the fluid out? If its like 2yr or more, go ahead and get some fresh in there. Sounds like a bleed issue. As mentioned maybe air pocket and you got it forced out so now the air dont compress.

I bled both brake systems about 1 year ago and the fluid is still a very good color in both reservoirs.

Exactly, i had a CCT and found that airpockets MUST be present , so @Vinish when opening the calipers, you moved the oil and that can remove or relocate a airbubble

3 weeks ago my friend who bought my CCT called me that the rear brake was stuck sollid, it was parked 4 weeks in his house, went there, bleed the brakes, and all working again .... 10 months prior i changed the brake fluids

The CC bikes have a air problem in brakes, thats for sure

My jackpot never have that problem, also the hammers have no airpockets problem, hence it is VERY difficult to initially prime a new hammer front brake properly also ( i put a hammer front end on my jackpot )

Just want to add, when i did my 4" foot control extensions on the jackpot it took forever to bleed the rear brake properly, once done it has been good for years ...

Yep, sounds like it's working right now. 11/2 inches sounds like an awful lot. I'd ride it.

You know the free play on a 12 XCT has an adjusting wheel on the lever right?

I would be seriously concerned about any bike that needed 1.5 inches of pull on the brake lever. I like to stop.

Thank you. Yes, I am aware of this and even with it adjusted to bring the lever as close to the grip as possible, the brake lever still reaches its stopping point substantially further from the grip than before I began that work which included replacing the tires.
