Need some advice on how to trouble shoot both the Parking Brake and the Brake Pedal. Traveling alot of mountain highways and have begun to have problems with Parking Brake not holding unless I forced it down to the last click available and then it will hold the bike.

The brake pedal is also beginning to feel spongy and I have ISCI Floorboards and their brake pedal and and I now so much play that the brake pedal actually is hitting the floor board. Scary.

What do I check and is there any adjustments that can be made on both Brakes to eliminate the play and make both of them secure?
