Merry Chrismas everyone.

 

I finally got around to fitting  312mm brakes to my car yesterday after bleeding the brakes I took it for a spin. Is it normal for the brake pedal to travel 3/4 of the way before I get any bite? I'm pretty sure I got all the air out the system, (i used a gunson pressure bleeder) it just seems like a lot of travel.

 

It's the first time i'be bleed brakes so i'm not 100% sure what to expect.

 

Cheers

When I use the gunson bleeder I also give the brake pedal a few squeezes to drive out any

Surplus air hanging around. Do you have braded hoses as these help firm things up too.

Did you bleed the entire system in pipe-run distance order, N/S/R, O/S/R, N/S/F, O/S/F?

 

If so it could be that the pedal will firm up after a few miles.

No it's not normal.

Me and my uncle fitted my 312's at his garage yesterday and they're so sharp. Barely have to touch the pedal for them to bite.

I fitted new pagid disks and pads and they felt great first touch of the pedal reversing off the ramp.

We changed my fluid for ATE super blue so it was really easy to tell when they were bled.

just so your aware the blue brake fluid isnt road legal ..... but yes the brakes should be fine from the go you probs have a bit of air left in them some where

I know, due to the chemicals in the colouring. If my brake fluid is leaking out of my car it won't be on the road anyway lol

It's really good stuff!

It's DOT4, in what way isn't it legal please?

 

I know it's been temporarily banned in the US since August, but here in the UK it's absolutely fine since DOT4 is a British specification!

It meets all specs ect mate. It's something in the colouring.

yep it is because it is coloured but i run it in my bike and it is very good stuff and easy to bleed through .... just something to be aware of if your car gets pulled by the plod often 

I think this is an urban myth, I can find absolutely no mention of it being illegal to use blue brake fluid if it meets all the formulation specifications here in the UK, it's widely available and states very clearly in the sales blurb that it's "especially suitable for highway use" since it is less hygroscopic and has a longer life than regular DOT4.

 

Unless someone can PROVE otherwise I think it's safe to assume that you can tell plod to f**k off if they make any stupid noises about it.

In fairness I think it would have to be an extremely clued up officer for it to cause a problem.

Apologies for spamming the thread anyway.

As said, I'd imagine you have a little air in the system somewhere.

That refers to the USA _jim, the clue's in the word 'color'!

Yeah thought I read somewhere that it's only illegal in America

many threads discussing this .... this is taken from one of them :
 

Take it from a VOSA inspector... 

It is illegal to use on a road going car... The dye properties that they impregnate the brake fluid with has not passed stringent UK government health and safety test and is very poisonous to a given PPM percentage for environmentally sensitive drainage systems....

I.e. As an example..... 

A motorway that runs near a protected river system and a collision occurs where a complete brake, wheel and suspension dislocates the flexible brake hose. That pretty blue dye ends up flowing down the nearest drain and inevitably to the river itself before the clean up crew can get there to act.

 

Incidentally it is not illegal to sell it in the UK and can be used on motorsport cars at motorsport facilities which have a dedicated drainage system by law to prevent contamination.

 

On a related note, that's why you see tankers that carry harmful chemicals on UK roads must have special rubberized blankets that seal the drains in the event of a leak. Not ideal, but at least its a safety feature until a contamination crew can stem the flow.

 

I hope this answers your questions

 

P.s. You can buy the very same brake fluid from ATE which is chemically identical, just without the dye, everyone wins!

However:

Where does it say that please?

 

You have to be REALLY careful about internet myth propagation, I hate to break this to you but an awful lot of people simply make stuff up to appear to be right, many even downright lie!

 

Please post a link to this discussion, this deserves closer scrutiny. MSDS sheets are independent scientific documents and if a manufacturer lies on an MSDS then they can expect massive fines and even imprisonment for those deemed culpable for the deception. I cannot imagine a global company as reputable as Continental GMBH telling porkies, can you?

I bleed the whole system with this stuff and the blue dye was great at showing you very clearly when the old fluid is bleed out. And by the way when it comes to changing the blue stuff they do a gold coloured one so you can tell the difference then after gold back to blue and so on.

You're going to have to be realllllly unlucky for the copper to find that you're using blue fluid haha

There firming up a bit now. They defiantly stop me a quick stamp on the pedal and my abs will kick in I just expected a firmer pedal. After all anyone who's driven a mk1 golf will know what spongy brakes are lol.

 

I think i'll will get some ate superblue and bleed them again for peace of mind, i'm just about to buy some braided hoses anyway so perfect excuse.

It's really cheap at eurocarparts at the moment

if it's spongy then there is air trapped in there. i agree with the comments about giving the brake pedal a couple of pumps to clear out any trapped air during the bleeding process... cant see the point of using blue fluid either, just use normal dot 4 fluid

Yeah I think you could be right I drove my boss's old passat and the brakes were deadly, as soon as you touch the pedal you'd get whiplash.

 

I'm gonna try the blue fluid just so i know when the old fluid is completely gone, i've never bled brakes before so I just want to make sure it's done right.

dont worry about that, you can see the new fluid come through, it much be noticably cleaner than the old stuff

+1 for eurocarparts....i had never used ate blue until recently and its the colour that makes the bleeding so simple. i will defo use it again.

Spongy brakes = air in system . It's a csae of bleed/bleed/bleed .
