67speeda Posted December 23, 2014 Report Share Posted December 23, 2014 So a while back my brakes were terrible. Got to the point it was downright unsafe. I did some searching and assumed the master cylinder was shot. Decided to do the hydroboost conversion while I was at it. I purchased a take off from ebay with the pump, lines, booster, and master cylinder. I ended up buying a new master cylinder though. Problem No. 1: The lines were far too short, ordered new lines Problem No 2: I am an idiot and didn't fully press the pulley on the new pump thus making a ton of noise. you guys helped me figure that out As i went to bleed the brakes i noticed the front brakes were shot. Searching on here i ended up doing the 07 Tahoe conversion. With all this done my brakes were maybe 10% better. Still Horrid. Problem 3: I searched and found i need the bleed the ABS unit. I did the old dirt road trick and bled them out. Brakes still suck I replaced all the flex lines (front with stainless) Brakes still sucked! Well over the weekend i left my truck in one spot and notice a little tiny pool of fluid in the rear. I thought I must have a leak in the new line. Nope! Blown caliper. Fluid was leaking and burning on the rotor. New brake caliper installed yesterday. WOAH! Brakes are amazing! good thing i had my seatbelt on when i tested them! Finally the truck stops well. Just wanted to let people know the 07 tahoe conversion and hydroboost is well worth the time and money. I am now very happy. but as my luck would have it, CEL just came on this morn and I can not find my scan tool! Thanks for all the help!

Downeast Johnny Posted December 23, 2014 Report Share Posted December 23, 2014 Gotta love a happy ending, at least as far as the brakes go. I've got all the parts to do the brake and hydroboost upgrade you've done plus I am putting all new hard lines on the truck. Sounds like your truck got to liking being worked on and had to crap out something to give you another project. Quote Link to comment Share on other sites More sharing options...
Cramer Posted December 23, 2014 Report Share Posted December 23, 2014 It's the best upgrade I did to mine! About the cel, did you jump the wires in the connector hat went to the old booster solenoid? That will cause a cel. Quote Link to comment Share on other sites More sharing options...
