Kia sephia: the rear brakes and a diagram..brake shoes..cylinder

I have a 01 kia...
I have a 01 kia sephia and I would like to have a step by step procedure to change the rear brakes and a diagram of the brake drum with components to install correctly new brake shoes,wheel cylinder and new hardware on this vehicle. Any help? thanks. Chuck Varner p.s are these cars known for brake calipers in the front causing drag or should I look to the rubber brake hose that installs to the caliper? This car has no retaining screws in the rotor. Somebody must have left them out. Would this cause a drag problem? Should I buy the screws and install them?

To address the front brake issue. Normally what happens is the front brake pads get hung up in the caliper frames,this causes the front brakes to drag. Take the pads out and clean up the brackets so the pads can move again and this should resolve any drag you may have.

As for the screws in the front rotors. These are only there to hold the rotors on during the cars ride down the assembly line and don't matter once the brake calipers and brackets are installed. Hope this helps!

Great explanation. I couldn't open the images though. Could you please send them again and I'll get you paid. Thanks. Chuck Varner

OK, I am going to try and send just the images in the order they appear. They really aren't that great and I think the one image I did get to you will probably help more then these:

Hello. I just got a call from my brother about his Kia again. Same symptom. He said it feels like the front wheel is dragging it takes more acceleration than normal to get the car to move. I have replaced everything On the front brakes. New rotors,calipers brake pads, both rubber brake hoses,new pads, new hardware. On the back I replaced both drums,new shoes, new hardware, new wheel cylinders. I wonder if he has a bad wheel bearing in the front. I just spoke to him on the phone. He says when he is driving down the road and applies the brake it feels like it grabs real hard then it quits. Next time he puts on the brake it might not do it again. The dragging problem I described earlier is causing his gas mileage to be cut in half. He also described another symptom that he hadn't told me about before. If he comes to a stop. Then turns the wheel hard then in either forward or reverse he hears a clunking noise. He might have a few problems going on hear. He drives this car to Pittsburgh PA. every day to work about 90 miles round trip. It has about 175000 mile on it. I told him that's an awful lot of miles for a Kia but he likes it. The brake problem is still driving me crazy. I didn't put a new master cylinder on it. Do the kia's have proportioning valves on them. If so where would it be located. Any help would be great. Thanks. Chuck Varner
Does the car pull when he is braking or does it stop straight?
Ask Your Own Kia Question
Customer reply replied 7 years ago
Stops straight.
Ok, I would check the brake light switch for starters. It may be applying the brakes on him if it is out of adjustment. This will cause the front brakes to grab and over heat.
With the banging sound turning the wheel, I would suspect a possible ball joint or strut bearing plate banging.
I will see if I can find a diagram of the proportioning valve for you and reply with it.
I just don't think that is the issue if it is stopping straight.
Also, if there is no howling or growling noise, a wheel bearing is unlikely. I have also seen master cylinders cause the front brakes to overheat and lock at times. It is rare, but it does happen.

Thanks for the diagram. I have been meaning to ask you. I owned a radiator a/c and automotive repair shop for 15 years but I had to shut it down 3 years ago because the steel mill in our town got bought out by a foreign company and he cut the workforce by 1200 men and I was one of them. I had 25 years in that mill. Any way I have a snap-on scanner that my cartridges are good up to 2000 and I was wondering if you knew of anybody that sells the updated cartridges? I don't need it to cover to 2010 maybe a couple years older like 2008. If you know of any place or anybody that does let me know. My email [email protected] And if you ever need cooling system advise or a/c advise let me know I'll do the best I can to help you. My grandfather started the first radiator shop in our little town back in 1946. So I have 38 years experience. Thanks again for all your help. If you email me I'll give you my cell number. I don't know how secure this site is. Thanks. Have a happy holiday season. Chuck Varner
I don't really know anyone who sells the cartridges,I would suggest ebay though, might just get a deal.
Personal contact is not allowed on the site.
You have a great Holiday Season as well Chuck. Sorry to hear about the job by the way.

Thanks. One more question about the kia. The brake switch you are referring to is the one under the dash that the brake pedal comes in contact with. Right? I don't know if this car has anti-lock brakes or not. If it doesn't This might not be the problem? I'm going to his house to check it out this morning. Thanks again. Chuck
Yes, it is on the pedal bracket. Make sure there is no pressure on it forcing the pedal on.
It should have an abs light on the dash if it has the abs.
If the brake switch isn't the problem,you may have to drive it until it gets hot, then back the nuts off that hold the master cylinder on. If the brakes free up after you do that, replace the master cylinder.
