'93 Vectra Front Brakes Locking Joe 1-17-10  
'93 Winnebago Vectra, fronts disc brakes lock and barely able to drive. When opening bleeders on both calipers fluid shoots out briefly then the wheels rotate normally until you apply brakes then again they lock up. Does the hydroboost in these have some sort of valve that could be preventing return flow from caliper? Plenty of fluid in MC and no unusual noises from PS pump. Appreciate any insight for this newbie RV owner!

Generally this is caused by the master cylinder not returning all the way. 2 "normal" causes. The pedal is not returning due to a miss-adjusted brake light switch, cruise control switch, bad spring, and so on. 2nd is the wrong length push rodbetween the booster and the master. If this is not the cause it is more than likely the master itself is faulty with a blocked or plugged port or two. Some one top up the system with the wrong fluid? Good Luck

Replace the 2 front flex rubber lines from the frame to the calipers about 40.oo each.. bleed replace with NEW dot 3 fluid---DONT do this on a damp or rainy day
you will be fine---

Should this problem happen to opposite corners or can is happen on only one? I have same problem but only one corner will grab. Used to be rear but new calipers & lines seemed to fix. Last year rt front smoked so replaced that caliper. Yesterday rt front smoked again. This has been driving me nuts! New hoses are next but what else should I look at?
