XJ700 Maxim brakes - what lever pressure is right?

I have an 86 XJ700 Maxim. I have replaced the brake lines with braided stainless lines, have replaced the pads, and drained, filled and bleed the system. I did note that the pistons needed a bit of force to get back into the calipers...even with the lines drained and bleeders opened.

I find that even with the dual disks, I have to pull the lever pretty hard to get significant braking. It is certainly not like a more modern bike where a 2-finger pull can send you over the bars.

Is this "normal" to have to exert what seems like the pull of a hand grip exerciser to get the brakes near lockup? The brakes are firm (I think I have the air out of the lines.

If the brakes are lacking compared to newer bikes, does anyone know of an upgrade that makes them stronger? You can't have too much braking!

Thanks in advance

 

I have disc brakes on the front wheel only. I have bled it and whatnot after removing and replacing my caliper up there. For me, I could probably put myself over my handle bars if I wanted to, but I won't. They are fairly sensitive but there's a lil play, too... I haven't ridden a "modern bike" and have nothing to compare to. Check the master cylinder for cracks or wear and make sure your line is secure. Also, make sure you have enough brake fluid in the reservoir.

 

Those Calipers should let you do a 3-Finger Stoppie.

I'd do a thorough Caliper Cleaning.

After taking-out the Caliper Pistons ... remove the Seals.
Make a Tool from an extra large paper clip.

Scrape the Channel-grooves that the Seal fits into.
Clean the groove like you're a Dentist working on a Super-model's smile.
Any "Tartar" or growth NOT part of the Caliper needs to be removed, until the groove is PERFECTLY Clean!

You said they were tough to get back-in.
All the stuff in the channel is why.

Clean the Caliper until you have it only alloy and nothing that doesn't belong.
ScotchBrite (Gray) the Cylinder.
Polish (Mothers) the Pistons
Clean-off with DiscBrake Kleen

Assemble parts using Clean Brake Fluid as lubricant!

 

Thanks for the replies! Looks like I have more work to do to get the brakes working like they should. I assume I'll need to get new seals too.

I really appreciate the information.

New seals on Brakes is always a good idea.
