Hello All,

  Finally New England is warming up. Took her out for a nice 100 mile ride. Ran great. My only concern is the rear brake seems to lock up easly. Doesn't take much pressure. Two-up. Is there a adjustment for this? Feels so good to be back out. Thanks

Let me add I only really use the rear when I'm goiong through towns. Stop and go to save some on the front.

Try putting some air in the system to soften the petal.
1) Free Owners Manual download: https://tinyurl.com/fmsz7hk9
2) Don't store your FJ with E10 fuel https://tinyurl.com/3cjrfct5
3) Replace your old stock rubber brake lines.

Scott,

There may be some pin-fine rust on the disk, which will go away with just a few hours of riding. 

If you can feel the rear brake "pulsing" when it is just barely engaged, then the rotor disk is warped, probably beyond the limits, and a new rotor is needed.  Check that none of the caliper mounting bolts are loose or broken.   If neither case applies there, then you may need to consider the age of the tires.  Tires do get hard with age, and if the tires are too old, the wheel will lock up too easily, with only moderate braking pressures.  I had old tires on my FJ (from the previous owner) which still had lots of tread left, but they were too old.  I hated to toss those old tires, but new tires gave me a whole new bike.  The improvement in handling was amazing, and well worth the price of new tires.

Cheers,
Red

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.

Nope no pulsing when applying the brakes, all bots are tight and I just put new shoes on her at the end of last season. Pirelli Scorpions.

I'm going to try Pats suggestion. I did bleed the rear brakes over the winter and put new fluid in. Maybe I bleed them to good.  :biggrin:

Instead of inducing air into the system which I don't think I would do, is to look into using a less aggressive pads. Might try some cheap pads ?

So I was thinking could the ABS in the rear be screwed up? Could I of put something back on the wrong way?
