i got done puting a 4.5in rc lift on my 90 when i put the rear break line extension bracket on i had to take the line off the clips that let it run the lenght of the frame the line seems that i couldnt even get another inch or so out of the line is it ok to have the line tight like that and has anyone else had this issue with this lift kit i dont want a snaped a break line its not super tight but defintly tighter

 

mine are tight when flexed. its better to have extra slack though. there is alot of cheap brake lines you can get from other trucks that are longer.

 

Better safe than sorry I would put a longer hose on it.
