Brakes squishy no leak

Mushy / squishy brakes are usually caused by the brake master cylinder seals failing. You can buy a rebuild kit or a re-built replacement master cylinder. I would recommend the rebuilt master cylinder as all the detail work has already been accomplished and it is not a huge expense. The key is to make sure that your use a bleeder kit to "Pre-bleed" the master kit before installation. Your making sure that the master cylinder is free of air before installation. If you instal it with air in the system it wil take you the better part of a quart of brake fluid to bleed the whole brake system via the wheel cylinders. What will happen is after you install the master cylinder the brakes would still be mushy and until you got the residual air out of all of the lines it would appear and act just like it did before you changed the master cylinder.

You may have some sticking calipers, or the master cylinder is going bad.
