1997 Chevrolet Blazer

Hey guys I am in trouble, basically I my brakes started to get hard to depress, not really hard but harder then usual, also when I depress the pedal it makes that air release sound like when you pump the brakes when the car is off, I just bled the brakes not to long ago, but one of the front brake lines came loose and I bled it but I didnt bleed the other front one but everything has been fine up until now, I looked at the brake fluid level and it was good but pretty dirty considering I flushed the brakes about 6 months ago maybe less. I checked the brake booster hose and check valve that runs from the booster to top of engine and I could only blow not suck, so that is good, any other ideas, any help is appreciated as this is me and my gf's only vehicle and we are broke! Also I am having another problem just incase it is related, I believe the code is p0102 low volt MAF circuit, I believe this is because I have a very weak battery that will die if I leave my lights on for more than 10 minutes. I am replacing this soon, can this have anything to do with it? Thanks.

 

sounds like the brake booster's internal diaphram is torn. You will need a new booster.

Get back to us after replacing the battery

 

Your brake booster is bad, may be causing the MAF problem as well as it is a vacuum leak

Just get one from a salvage yard, they dont go bad all that often

 

Thanks guys I just posted a video in the tech section if anyone needs itt, sorry about the title I didnt get to finish it lol, \\
