Now it is doing it again. The pedal goes almost to the floor and then grabs, and stops the truck? Any suggestions on what it could be? I need new front pads, but the rear shoes looked good, and the rears seemed adjusted correctly. Mike Re: Brakes Qestion?

You could have an internal leak in the master cylinder, which could behave as you describe. It is not uncommon for master cylinders to fail right after bleeding- the reason? Using pumping to bleed the brakes sends the piston seals into a rough, contaminated area in the master cylinder, damaging them. It doesn't take long after that. Ask me how I know... <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> That's why I really like pressure or vacuum bleeders so much. -Bill '87 4Runner w/ '96 5VZ-FE, 'Red Chili II' '97 Taco XtraCab 3RZ-FE, 'BlackBean' TLCA # 13257, Rising Sun 4x4 Club Land Use Coordinator "He who stops being better stops being good." -Oliver Cromwell Moderated by  4Crawler, 4x4Wire, kewlynx  Hop To Mitsubishi Forums ------  Mitsubishi 4x4 and SUV Tech  Mitsubishi Diesels  Mitsubishi ArchiveToyota Forums ------  Early Toyota Trucks  Toyota 4Runner, FJ Cruiser &...  T100 & Tundra Forum  Tacoma Forum  Toyota Tech ArchiveJeep Forums ------  Jeep Talk  Jeep TechIsuzu Forums ------  Isuzu 4x4 & SUV Talk  Isuzu 4x4 & SUV Tech  Isuzu DieselsKia Forums ------  Kia Talk  Kia Sportage & Sorento TechOff Topic Chat ------  4x4 Gallery  Off-Topic Chat  Recreational Access & Land ...  Politics4xForums ------  Outdoor Gear  General 4x4 Discussion  Tools and Fabrication  General Communications  Amateur Radio  GPS and MapsParts Bin ------  Private Party - Garage Sale  Private Party - Items wanted  Vendors, Hot Deals, Group Buys4x4Wire Back Yard ------  Suzuki Forum  AZ Crawler Crew  Cal-Nev Crew  General Ford 4x4 & SUV Forum  General Dodge 4x4 & SUV Forum  General Chevy 4x4 & SUV ForumFeedback & Testing ------  Problems, Questions, Suggestions4x4Wire Staff ------  Forum Moderators  Problem Threads Print Thread Switch to Threaded Mode 5 Excellent 4 Good 3 Average 2 Bad 1 Terrible View Profile Private Message Follow User Forum Posts View Profile Private Message Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts View Profile Private Message Follow User Forum Posts
