Got an x type 2.0 2005 in today and after replacing both rear metal brake pipes and bleeding the brakes the pedal seems to stick down a little and the stop lamps stay on and all four calipers are pressurized...the only way you can release the brakes is by slackening off the master cylinder bolts and the brakes come off...if you then re-tighten the bolts the brakes don't then re-stick unless you apply the brake a few times.... I've seen this is a common problem by doing a Google search but have not seen any suggestions on how to rectify it. can someone help?  |

No it's located on the nearside.....i have researched a bit more and some suggest that the brake servo could be causing it... but cant see how bleeding the brakes should cause it to fail!

How did you bleed the brakes??
Did you use a pressure/vacuum bleeder or did you manually bleed them???

Not any direct help to you, but many moons agao when the Astra F used to lose it breaks by simply changing the pads or a rear wheel cylinder the Vx area tech's came up with the flipped master cylinder seals. Try telling that to anyone who knows there stuff. I've had it happen to me so often I used to keep a cylinder in stock. I've stripped many down and never ever found any flipped seals. I have found if you left them with all 4 bleed nipples open all night with the reservoir topped up that when you came to them in the morning you have a break pedal. Not always possible I know but cheaper than a cylinder. I would very much like to know why it happens though!

The brake pedal is fine and they were pressure bled then manually bled because the pedal was spongey i'm wondering if the the servo is sticking due to being moved more than it normally would because the brake pedal would be pushed down further when bleeding.

The way I've been caught is if you bleed them manually, the master cyl plunger/seals get stuck/drag the sh*t from going further down and start causing all sort of issues.
It's only happened to me a couple of times, but it was on old sheds that hadn't had the fluid changed on for years.
