Morning I managed with some difficulty to remove the flexi hose ,thinking it was blocked .However blowing through it the hose seems quite clear .Ive sealed the master cylinder reservoir with cling film to stop it leaking.The next job is to see if fluid pours out of the brake pipe,when I remove the seal Ive always found this happens when the flexi is disconnected .The master cylinder looks quite new .We have a visitor so on hold Len
