Has anybody got any ideas on bleeding brakes for the first time? I have been at it for a fair while now and they are still really spongy, no leaks or nothing though, is it just a case of perseverence due to being new?

Gunson ezbleed is a good cheap system, it has a header tank of fluid which is pressurised by attaching it to your spare trye. it forces fluid through the system, and all you do is open the bleed nipples. You should be able to bleed the brakes in the normal way. have you got rear drums or disc? off what donor?

Have you fitted the calipers on the correct sides, bleed nipples at the top?

Did you fit new flexible hoses? If they're old or too long, they can expand enough to make the pedal feel spongy.

When you hold your foot on the pedal, does it stay put or does it slowly sink (damaged MC seal letting fluid bleed back into reservoir - no external leak).

Gunson's ezbleed a good idea - or wife if she's instructable

If you use the Easibleed let some air out of the tyre, down to about 15-20psi and do the wheel cylinders in order furthest to nearest to the master cylinder. N/S rear, O/S rear, N/S front O/S front.
