Complete Brake Fluid Replacement
- Thread starter shaggy_master
- Start date
Had a go at the gunson eezibleed. If anyone has just baught one i hope you kept the reciept.
None of the master cylinder caps fit. I took a spare skyline one and stuck a hole in the lid for the pipe. It wont seal. The pipe on the lid does but the lid on the fluid resovoir doesnt.Tried sticking more rubber under it but it will not seal.
Ive now replaced the two front calipers and bled them. I went to do the rears but the neighbours kept wanting past so it couldnt be done. Bless them with their garages and me stuck in the backlane. Assholes.
Now, the brakes are even worse. With the engine on the pedal can hit the floor. I can still make the tyres chirp if i slam on but its not exactly dramatic.
Here is a video of the situation now:

It starts with the engine running. The pedal can hit the floor. I pump it a bit but its still crap. Then, i turn the engine off and after a pump or two its rock hard. I then start the engine again and the pedal sinks. At the end i show how bad it is by using my hand to push the pedal half of the way down.
Idea's?
oh, for the record the master cylinder doesnt have a bleed nipple. my skyline did and it had the same problem.

Some of the tools draw fluid from the bleed nipple. I like this idea as there's no vacuum seal problems on the master cylinder and you can do it all while you watch the fluid come out. They say an operational pressure of 70-120PSI is needed.
Spotted this electric compressor. '250PSI' it says and seems to be saying it's not just for tyres - http://cgi.ebay.co.uk/12V-Car-Auto-...Compressors&hash=item3365901a6b#ht_1463wt_906
Does anyone think this'll handle useage on a tool like this - http://cgi.ebay.co.uk/Sealey-Brake-...ultDomain_3&hash=item19c33af3b1#ht_1355wt_906
Reviews on products like this seem to be few and far between.
Then there's this manual pump tool - http://www.eurocarparts.com/ecp/p/t...ine-tools/pressure-testing/?SEAVS402&0&t5_419 Could be handy?
Also any input from people who work in garages and do brake bleeding would be much appreciated. Wezz, Dan, Simcard? What tools do you use?

ed those vacuum tools work great if you have a good compressor or fixed airlines in your place of work, and i don't think that little compressor you linked can provide near the required litres per minute. i've never seen the hand operated one in action to say definitively but it looks to work on the same principal just using hand power to create the vacuum so should work ok if your strong enough lol. i personally have 2 types of brake/clutch bleeder a oneway valve type and a compressed air push through type and i always reach for the oneway valve one 
Yeah as I say I dont like the push through idea as they seem to not always seal ok, and the one way valve I've used i havnt had luck with (probably due to air being sucked back in through the nipple thread). I dont want to spend the money on a compressor so i'm really hoping to get feedback on the hand pump tool. But it seems no one's used one so I might have to just risk it and try it.
that's a bloody good buy! my 3hp compressor cost almost three times that!
oh yeah the airtools make life so much easier sometimes :shades:

Further to this, I bought a hand vacuum tester that doubles as a brake/clutch bleeding kit. Tried it out yesterday for the first time. Great tool, easy to use and great results. It can create enough vacuum to allow you to draw through enough fluid to fill the pump's reservoir without the need to re-pump. So you can just top up the master cylinder reservoir as needed.
A point to note for the phase 2 N16s fitted with EBD is that this worked well with them. Normal foot pumping tends to not get decent results due to all of the lines and valves and what not that the EBD has.
The trial yesterday was on an N15 GTi and worked well on that.
Here's the kit options. I bought the more expensive Draper kit due to it's studier looking handle.
