Hi All,
I currently have brakes that are somewhat squishy. However, if I bleed the Front right brake caliper it goes back to like it should, but returns to its normal self after a few pumps of the pedal.

Is the problem in the master cylinder, or in the caliper?

Cheers

Could have a leaking rear wheel cylinder thats causing the problem any damp around the drum when you blead the rear brake.

The brake lines are usually connected diagonally. If you are bleeding the front right. The rear left is the one you need to look at and visa versa.

Not sure I follow! Bleeding the front right brake rids of air that was let in at the left rear?

Surely then, there would never be a need to bleed the rear brakes?!

Your air leak is at the rear and as you take the air bubbles out of the front new ones are being made by the hole in the rear and you bleeding it is sucking them through the pipe making your brakes squishy again.

When I bleed the front brake, the pedal goes HARD. Then, after driving for a while, it goes squishy again.

So the leak isnt in the rear?

Doesn't need to be a leak, just air. You should always bleed all four corners, starting with the furthest from the master cylinder unless the workshop manual says otherwise.

Is there a reason that you are only bleeding one caliper? Normal practice is to bleed all four corners?
