|A slotted fastener? C'mon Shimano! Really?|
But all at once? I had great rear brake feel, then bad brake feel all in the same ride. Well, I decided to hedge my bets and I got both the brake bleed kit, mineral oil fluid, and a new set of organic pads.
I figured on changing the pads first as that is the easiest fix. As I sat down to work on this, I discovered that the brake pad retention bolt had a slotted head. Not a hex interface, not a Torx interface, a slotted interface. What?!!
Warning! Rant Alert: As a mechanic it is my opinion that slotted interfaces should be banished from Planet Earth. There is no reason to use that anymore when superior technology exists and is extensively used in the industry. Why do I feel this way? Because a slotted interface fastener is super easy to damage, harder to work with, and .....well.....it just is not a good choice anymore. As stated above, better ideas exist and are readily available to any manufacturer. Okay....rant over.
Once I had carefully selected the proper size flat blade screwdriver, the fastener came out undamaged. Whew! That was the worst of the job right there, and the rest was a breeze to finish up. I buttoned up everything and went out to bed in the pads to the rotor.
And how did that go? Well, the brakes are better. But they are not what they were yet, so I may do a brake bleed anyway just to see if I can't bring the lever feel back to what it was. I mean, I can lock up the rear wheel and braking power, modulation, and all is just fine. It's the pad contact feel that is lacking and it seems to me that the lever travel is just a bit much yet. But here again, I've had Shimano road brakes on many bikes in my workstand where you couldn't get the rear to feel like the front no matter how much you bled the brakes.
And I had zero evidence of brake fluid leakage, which would indicate that the system is still sealed, but that doesn't necessarily mean anything here. It just points to the fact that it was mostly the pads that went away, but there may be something else going on here.
Stay tuned. I may end up bleeding the brakes after all.
