snailman153624 167 Report post Posted August 4, 2013 By vacuum pump, did you mean brake booster? I would suspect either your brake booster, or the check valve in the hose going to the booster is bad. I have never seen a diesel 626, though, so it might be a bit different from a gas/petrol model. Quote Share this post Link to post Share on other sites
Jamesyboy32 0 Report post Posted August 5, 2013 Think the petrol and diesel are different. The vacuum pump is beside the camshaft. The brake servo runs from the foot pedal to the back of engine left hand side as you look at it(im in uk) Quote Share this post Link to post Share on other sites
