Brake hoses & Replacement

Brake hoses are the hose that connects from the sprung part of the vehicle to the unsprung part of the vehicle, the brake calipers/drums.  This means that as the wheels move around, the hose needs to be able to flex in order to still provide pressure to the brakes.  It will usually sit from the pipe near a strut or lower control arm, straight to the brakes.  It is made of a rubber hose, braiding around, then a thick rubber on top.  They can damage quite easily, and need to be replaced as soon as they are damaged or worn.  This includes cracks, chips, discoloration, etc.  The reason is that if the hose starts to leak, it's a safety risk as the brakes may fail to operate

During WoF inspections,  make sure to inspect the hose very well.  Turn it around to find cracks or discolouration.  Use a torch so you can see. 


This is the bottom bolt.  This is not a usualy bolt, it has holes in it which the fluid passes through.  The bleeder nipple is also right above it.

To replace the hose,  remove the wheel.  Remove the clips using wire cutters.  Clamp the hose down so it doesn't leak out fluid.  Use a flare wrench (Always) to remove the top nut then remove then remove the bottom nut.  Fluid will come out so be careful.  When replacing the hose with a new one, leave the labels on it, so if it fails, it is easily tracked down to where it has been bought.
