No rear brake

Welcome to the forum.

Did you bleed the brakes after you put it all back together? You should have gotten a bunch of fluid out when you bled them.

Hey Tigger. Tried to bleed the rear brake but little to no fluid came out.

Are you sure you got the piston spring in the right way? If I remember the small end goes toward the piston cup. If it's backwards there will be no fluid pumping action. You can try loosening the banjo bolt on the master cylinder and pump it to get some fluid running out before trying to bleed the brakes. Sometimes the cylinder will be difficult to fill at first. Also did you check the small port between the reservoir and the cylinder bore? If that little hole is plugged you can't bleed the system.

Hi Exavid. Not sure what piston spring you're refering to. There is no spring in the caliper that I took apart.

My error - For some reason I thought you'd worked on the rear master cylinder. I'm really beginning to suffer from A. G. E.

You need to check if your rear master cylinder is working, chances are it is all festy and needs re kitting.
