posted this question before but here goes

 

cant seem to bleed the system doing it as per manual but got a prob

have assistant in car to press pedal does this and i open correct nipple fluid spurts out pedal goes down close nipple

assistant takes foot off pedal pumps again and holds down open nipple nothing comes out and no fluid has left the master cylinder this can happen a doz times pedal soft

assistant takes foot off pedal and gets out still same amount of fluid in master cylinder never drops after 12 goes

this is the funny thing get back in car after say 10 mins pedal as hard as a rock brakes normal no pumping

totally mistified can some one help ive 2 rear calipers to fit and a new master cylinder reluctant to start job till i can sort this out the more u use the pedal on a journey the better it gets

 

ps never had this prob till mot garage fit a new front nearside short pipe not been same since

dont want to go back to them there usless

have you bled the abs pump in the boot ?

yep same happens first bleed u get fluid after that nothing

So, after the garage fitted the new near side pipe,were the brakes ok? or did this leave you with the current problem?

Just trying to understand the history as they may have caused the problem having had to break into the system.

they were ok till I came to change some pads then the pro arose i have brakes but the pedal varies from day to day somtimes it travels a bit other times its good totally miffed cant understand it espescially the master cylinder bit where the fluid dont drop

If you forced the pistons in to take the new pads it can sometimes invert the seals, this could be the problem.

never actuall got the new pads inn thought id bleed first to solve the spongy pedal

is it possible that the garage could have done this?

dont think so the only replaced a pipe no pads so would only have had to bleed the system

ok, i'm out of ideas lol. Bring on Jeff.

Is there no one can help please!!!!!!!!!!!!!!

am bleeding my brakes at the mo when i was doing the front i was pumpin them for ages and the fluid in the master wasnt going down was less than half full but when i topped it up for full then pumped the brakes the fluid level went down and the brake bleed ok i also recomend this http://www.ebay.co.uk/itm/171050178411?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

i have used them for years and there great

I'd say that either the pipe is not on tight enough and is letting air in OR the seals have gone in your BMC. If the Garage changed the pipe then surely the should have bled at least the corner they did? Take it back to them and get them to sort it, as it sounds like they've done a half arsed job on it mate.

 

EDIT: Just seen that you don't want to go back to them, which is fair enough. Is there not another reputable garage near you? It shouldn't cost much to get it looked at and sorted.
