My brakes are not applying to well. I need to push the brakes to the floor to get any stopping. i am thinking of changing the master cyclinder. I don;t think brake lines have a leak cause they are steel braide. but my one wheel is really gressy and theres sand on the inside of rims. HELP!!!!!!!!!!!!!!!!

 

Try the master cylinder. and see if that cures the problem. If not check for leaks around the lines. Also check the condition of the pistons if the problem persits. The grease inside of your rim is most likely CV grease from the axle. Check for a rp in the boot and replace if necessary. Good luck.

 

yea and umm should i bleed the lines just in case?

 

You'll have to bleed the lines if you swap master cylinders or calipers

 

THANKS MAN IT WORKS LIKE A CHARM NOW
