Hi,
I am having an issue with my front brake. 90% of the time when I apply the front brakes I get a good solid response from the brake lever / brake actuation. 10% of the time the Brake lever travels 2/3rd of the way towards the grip prior to actuating the brakes. I still get brakes towards the end of the throw but it is not great and it hits the grip.
Some background: I just bought the bike with approx 9000 miles on it. When I first noticed this problem I found out that my front brake master cylinder was leaking. I bought a replacement piston for it, honed the master cylinder bore out and put it back together. I spent some quality time bleeding it and it worked…. Until the same problem came back to haunt me. Since that point I have spent some serious quality time bleeding both front brakes and the ABS unit. I had some air come out initially and now I am just pushing clean brake fluid through the system. I have also checked the master cylinder and it is not leaking.
What is weird to me is that once I notice a lack of resistance when pulling the brake lever I let it go and when I pull it again I have full brakes.
Normally I would attribute this to air in the system but it is weird that it only happens once in a while.
I did check that both rotors are still “floating” freely for whatever that is worth
Any thoughts would be welcome
Cheers!!
