How Much Suction......

Should I expect from me vacumn pump?
Problem is my brake pedal comes and goes a bit, when you start up in the morning the pedal is long but after you drive it for a bit the pedal comes back to normal but drive it and use the brakes alot and the pedal goes long again so i suspected me vacumn pump, took the hose off the master cylinder and it hardly sucks your finger onto the pipe.
Im guessin it should be better than this????

id say vac pump mate as only this conrols that also check for perrished hoses

VAC pump but also it could be your master cylinder ! , do you have drum rear ? , whats the adjustment like ? ( not adjusted up will give you long travel , but braking a lot will keep the shoes out , so giving you normal travel ) .

Thanks for the replies folks. sorry I have just come back from Bicster on a training course, yes i have drum rears and the adjustment seems to be fine but will look further into it this weekend

try the check valve 1st. It should only work one way. may be that. cheaper than the pump anywho!

200 or 300? my 300 went on xmas day! typical
