Front brake and Caliper question
I am needing to know some info about my brakes because last year I had to have some rear brake line work done on the rear axle along with adding new front rotors and brakes on my Achieva but when it came time to bleeding the brakes after all of that work was done my friend had to bleed the front brakes threw the banjo bolts due to broken off bleeder screws. So ever since I had the brake work done my brakes feel on the soft side and it take awhile to slow down when I get out on the highway because it acts like I have no brakes at all when it come time to slow down for the exits or I may come to a traffic jam, also it does the same thing around the city but not as bad when it come to the highway. So does this mean I still have air in my lines a year later or does this point to a possible front caliper problem since I do believe the front calipers are still original. A little not I am gonna add, that note is the entire rear braking system had been replaced ranging from new metal and rubber brake lines to new drums along with new shoes and hardware. Almost forgot but the wheel cylinders were replaced to. Also when it come to the front brakes I'm already needing a third set within a years time. So does this problem point to a mechanical problem with my brakes or do I just need to have my brakes bleed again. Thanks.

you cant bleed the brakes through the banjo bolts, the bleeders are installed at the highest point on the caliper. you will have to get some new bleeders and get the old ones off.

So could that be why my brakes are the way they are? Also what would be a good way to get the bleeder screw out or should I just buy new calipers.

depends on the car, some are cheap enough to just get calipers because its not worth the effort. if the calipers are expensive i would take it off so i could put it in the vise pointed down so drill shavings come out, and use a extractor set.

The calipers are cheap for my car, they are 15.99 per side with a 20 dollar core. So I think that may be the better way to go. Also should I replace the brake lines to or not.

That is exactly why your brakes are the way they are. Air rises to the highest point of the caliper. Bleeding at the banjo bolt, which is fairly low on the caliper, will leave a significant amount of air in the calipers. The other thing that concerns me is if the bleeder screws were broken off, unless you plugged them with something that is an open path for air into the caliper, and for brake fluid out of the caliper. If they are open to the air you can't build any pressure al all. Not good. I am surprised you have any brakes at all.
Get new bleeder screws in there, or get new calipers.

I will be picking up some new calipers over the weekend along with replacing my hood and bumper due to a few months ago I ended up rear ending a Chevy truck due to I feel asleep.

thats no good, i would look down the core support and along the inner fender for straightness while it was apart, you wouldnt want any surprises

That was the plan to look at those areas. These Achieva'* are rare cars and very hard to find I have found out after I bought it. I have only seen 3 others like mine, A sport coupe design which is a 2 door and the others were the SL 4 door series like mine. Also getting parts to for it has been another big headache to due to a few I was needing for my car was vendor only items and wow GM was sure proud of there parts price wise. I didn't want to spend that kind of money but I needed them to keep the car running.
