are u suppose to bleed your brakes a certain way after changing proportioning valve

 

Yes you must bleed the system starting with the wheel furthest away moving to the wheel closest. Search for a DIY

 

did that and pedal still spongy

 

Are you leaky fluid from somewhere?? Are you making sure the res stays full during the bleeding process. You make have to do it 2 or 3 times to get pedal hard again

 

ill try to bleed it again and see if it help thanks

 

Also, how are you bleeding them???

 

A full system bleeding job done properly usually takes 2 people and about 15-20 mins. Are you doing it by yourself? If you are theres no way your doing it right, you are probably making it worse. Also if you have a proportioning valve/block with air in it you might want to tap it gently with a screwdriver handle to dislodge any bubbles that might be stuck, same with master cylinder.
