Changing brake lines on the mk1

This guide will show you how to replace your brake lines if they are damaged or leaking.,

you'll need to remove the wheel and jack up the car first,


This is what the new brake line will look like,

Now your gonna have to pressurise the system, sounds difficult but its not really.
You will need another person to sit in the car and press the pedal for you though while you are opening/closing the bleed valve,.,

First you will have the valve open (it just needs a little turn) and get the helper to pump the brake pedal until there is a nice stream of brake fluid comming out and not just spitting, then while there doing that you tighten it and see if they notice a difference in the pedal,
Keep a bottle of brake fluid handy and make sure the reservoir doesnt get too low.,.,
Tell them to keep pumping while the valve is closed then tell them to hold the pedal down., you will now open and then close the valve, releasing the pressure and remaining air in the system, make sure that the helper is still holding the pedal down while you close the valve or it will suck in more air.,
When the valve is closed tell them to pump the brake again and they should feel it stopping about halfway down,.,.
Depending on the amound of air in the system you may have to repeat the process to get all the air out..,

Be sure to clean any spilled brake fluid off the discs, pads etc or the brakes will be useless.,


Job well done!.,.,

Re: Changing breaklines on the mk1

great guide.

Its worth noting that the break lines have a nasty habit of rounding off, requiring you to replace the metal line all the way back to the master cylinder (well, at least for the front of the car)

So lots of penetrating fluid and a wire brush before attempting removal will help. Also ensure a proper brake line (flare) spanner is used to minimise the likelyhood of this happening. I've found a 'racheting flare spanner' (part number VS0342) worked well.

Re: Changing breaklines on the mk1

Good guide mate!

I had the displeasure of having to do a full brakeline replacement when I invested in my MK1...

Total pain in the ass!

Re: Changing breaklines on the mk1

front rubber brake pipes from a mk1 punto and mk2 are not exactly the same but will fit either car normally, if you will call the shop they will tell u its not gonna fit (mk2 pipe costs more compared to a mk1) while in reality it does, took front rubber brake pipe from a mk2 and installed it on a mk1 with no problem
