Brake imbalance help!
Hi,
My dad has a hyundai lantra 1998. It failed its mot due to a brake imbalance. I was told that it was the rear left wheel(NS rear).
I had a look at the car for my dad and tried to bleed the cylinder at the back before I started and got hardly any fluid out and a lot of air. I stopped and removed the drum.
The adjuster was frozen and the cylinder was leaking and the springs looked a bit rusty.
I replaced the brake cylinder, the springs and cleaned up the adjuster and all looked good. I then started to bleed the brakes and it took a while before I got any flow of fluid. I was using a hand held bleeder with a pressure gauge. I spent about half an hour trying to bleed the cylinder and the flow was not very good from this wheel? I started bleeding the other rear wheel and it was easy bleeding this wheel, hardly any effort and a good flow and not really dropping or requiring many pumps with the hand bleeder compared to the wheel with the issue mentioned.
Still convinced something is not correct I put my foot on the foot brake and the brake pedal is solid. It's not soft and it does not move to the floor. I took the car for a test drive and the car seemed to brake ok.
I wanted to check that the brakes were ok before it went back into the mot station for the re-test after the work I done. And the local garage I took it to said that I have a brake imbalance on the car.
I have attached the sheet to this question and any advise would be appreciated to what else it could be? As I said it was difficult getting a good flow of fluid from that wheel.
The car does not seem to be loosing any brake fluid?
Thanks for any suggestions.
Regards,
Ross

I can give this a go tomorrow. I just wanted to o check my understanding. If I put the car up on a set of axle stands. Put the car in reverse and run at about 5mph and brake and get someone to watch both rear wheels.
The wheel that stops last I should then move the adjuster on to move the pads closer to the drum and repeat the process until both wheels stop at the same time.
That sounds like a good idea. I can give it a try.
My only other thought was the flexible hose as I was having trouble bleeding that wheel?
