Default 06 pt cruiser brake booster

Hi guys... I really need some help. The brake pedal got really hard and I could barely stop the car. Someone told me it was the brake booster? Since I didn't have $500 to take it somewhere... I decided to try to tackle it myself. I am a girl with some good fixit skills..lol. Anyway... I bought a used booster on eBay for $30 and it was listed as 2006-2010 pt cruiser booster. I was able to install it fine but now I can't bleed the brakes? No fluid coming out of 3 of the 4 bleeder screws? I tried bench bleeding master cylinder but still can't get fluid out of the bleeder screws? It seems like the booster is not pushing all the way for the air to come out. I'm wondering if I have wrong booster? Does it matter if the car has ABS? Mine doesn't.. but maybe the car it came from does? I'm really stumped. Any ideas? I just bought this car... brought it home and bamm... no brakes? Plz help?
Oh... does starting car help in any way?

Before changing the booster did you check the vacuum lines to the booster? If the booster is not getting vacuum it won't work. I would start the car. Without the car running any vacuum created will would bleed off when pressing the brake pedal

Before changing the booster, you probably should have checked the master cylinder. Boosters usually don't go bad. Do you recall if the brake pedal would move when you started the car if you had your foot on it? Generally, an easy test is to put your foot on the brake pedal with a light pressure on it. Start the engine and if the brake pedal moves down, the booster is good. If it's stiff, the master cylinder needs to be checked. It sounds more to me like you have a faulty master cylinder and not the booster. Is the rod adjustable for the master cylinder and if so, did you change that? Open the bleeder screws on every wheel cylinder/brake caliper and just see if any fluid weeps from them. Post back and let us know how many miles are on your PT and what else you've tried.

Thanks for all your help. The car has 96K miles on it. I got in car to move it & brake pedal was super stiff... couldn't hardly stop the car without both feet & all my strength. I stopped by pep boys near my house & the guy told me it had the characteristics of a bad booster. None of my previous cars had a booster so this was all new to me? After playing with it for a few days I started to think that maybe the problem was in the master cylinder too. I haven't tried anything else yet cause I really didn't know where to start? I guess I will check out the master cylinder & go from there? I'll keep u posted. Thx again! The rod is not adjustable.
The car is 2006 pt cruiser, base wagon, Automatic trans, 96K
I have already tried opening all the bleeders... nothing. I got fluid from only the rear right

Okay, I'm not an ASE Certified mechanic nor am I a mechanic at all. SO, I'm hoping one of the other members that IS a mechanic will chime in and be able to help you. I don't understand why just opening the bleeders and letting the lines gravity feed won't produce fluid at each wheel. Are you removing the reservoir cap when you do this? Dsab had a very good suggestion when he mentioned checking all of your vacuum hoses too. If you're not getting vacuum to the booster, it's not going to work. And of course, you bought a used booster, so that could be defective too. I do the same thing with parts and sometimes it comes back and bites me in the ass.

I had a similar issue but with the clutch pedal, but the quick-disconnect fitting from the slave cylinder had come off. sorry dont have any idea about the brake because ive never had a brake booster fail with the pedal hard it usually goes to the floor or makes a wooshing sound.

I tend to check the easiest solutions 1st in this case vacuum hoses and connections. If the bleeder screws are not allowing fluid to come out my 1st thought is they may be plugged which can happen if they were not capped. You could remove the bleeder screws and clean them out with a piece of wire or replace them with new ones as they're not expensive

I agree used parts can be hit or miss

Sometimes, even removing the bleeder screw won't produce a drip. If the brake fluid has never been changed, the crud can seal the opening. I had that problem with mine. I used a 12" C-clamp and cranked that sum beech down and the fluid came shooting out like a rocket. And it was NASTY. I just went ahead and bled each wheel and changed the fluid. I can't tell any difference in the brakes, but at least I know the fluid is good for a while.

Welcome to the forum

I commend you for trying to tackle your own repair, but it sounds like you should have gotten a better diagnosis from Pep Boy's. Did they actually look at your car, or just go off what you were trying to describe to them?

It's very possible that you got the wrong booster. Maybe you got one for a first gen PT which run from 01-05. They are different from the 2nd gen PT boosters. It doesn't make any difference if you have ABS or not, as long as you got the right year booster. For around $80 plus your old one as a core, you can get a new one from O'Reilly Auto Parts. Maybe that's the route you should go as it seems that either the one you got is no good or not the correct one. Any way to get your money back from the seller off eBay?
