    Default Please help

    we keep having to bleed our brakes.. we had the front ones changed just over a year ago and ever since then we keep getting air in them, had the pipes looked and they seem fine.. we are NOT losing any brake fluid.. getting fed up with having to bleed them.. it seems the pedal travel (and I mean travel .. push it again to make them hard & work) happens when wet/snow.. my OH reckons its when the traction control light comes on they start getting air in but ive never noticed.. there was no problem with the braking system before they got changed but we knew the fronts needed doing.. what could it be??? it can go for months after bled then all of a sudden it starts, then slowly gets worse..

    The bolt is clearly visible..at the end of the brake line,where it attaches to the caliper.

    Air in the ABS pump possibly...

    Only way to sort this is to use Tech 2 to open the ABS valves whilst doing a bleed (Op-com doesn't do it for some reason, well mine doesn't!)

    Or start the engine and bleed the brakes. This is the way I did my dti many a time and always got a good pedal

    Only other suggestion is that either the master or slave cylinder is knackered, in my experience this is a possibility.
