Brakes..

[shokenore]

Many thanks for the tip, what's an lspv?

It's going back to Kwik Fit for them to have another go at it....

They say they never normally syphon off the excess fluid when they've pressure filled it, as there should be no pressure in the master cylinder, so being above the Max mark doesn't matter. Does everyone agree with that?

I don't think they earned the nickname of shit fit for nothing.
You left the depot and then found brake fluid everywhere?

[Tonka]

Yeah, only when I'd got home though. MS cap loose and fluid down inner wing etc

My suggestion would be to take some photos of the cap and the fluid and get back there tommorow and get them to sort it out.
They have an obligation to sort out the brakes and to sort out the mess.
Doesn't brake fluid strip paint?
What if you hadn't noticed the master cylinder cap off and lost all your braking and ploughed into the school kids at the the bus stop?
If they can't even put a master cylinder seal back on no wonder your brakes don't work.
Fcukers want stringing up.

I would create merry hell if they started to play silly buggers.





But after saying all that I hope you get the brakes sorted.
Get them to check the brake lines in the chassis corner before the lines pop up to the rear axle.

Why, is that where air bubbles get stuck?
Many thanks for your advice.

[shokenore]

If I read your post correctly you said you used a lot of fluid and the brakes are still not right.
The brakes lines can corrode in that area.
Have a look for damp patch on the floor just in front of the drivers side rear wheel or if you can get underneath have a look for any corrosion or dampness.

There's an inspection hole under the driver's side rear seat base to check the brake pipes behind the fuel tank.

[Tonka]

Right, I'll have a look, thanks. The pedal was ok before I started all this though, so I think the problem should be in the bleeding. Unless somewhere somethings been damaged of course....

You might find that the bubbles are coming from around the bleed nipple threads when you loosen it for bleeding and not the brake system itself.
If you only just crack the bleed nipple open a bit then press down on it it might stop the air getting in around the threads when you back off the pedel pressure. You could also put a bit of ptfe tape around the thread.
Also check the tube on your bleeder is a tight fit on the bleed nipple.
I blead a bike front brake once and put loads of fluid through it before I realized what was happening.
Hope this helps.

Putting a bit of PTFE on bleed nipple means removing the bleeder plug? Will fluid not flow freely? Mine is always damp at bleeder plug.

Same with the one I was working on. Spongy pedal and if used a lot the pedal drops. Apparently a new master cylinder was installed a while back by someone else, but the problem persisted. Then the old master was rekitted and no better. I'll let you know if I find out what the problem is.

Nev.

My LSVP was leaking for quite sometime now. Just recently I noticed the pedal drops intermittently (once in 10 pedals). Is it OK to bypass the LSVP?

Thanks,

personally I wouldn't, you'll get to much brake pressure under a light load to rears and will likely lock them up if braking in a hurry.

I think I have one in the garage off my Gen2 2.4 should you want a used one (PS not the reason for my statement above ).

[chardspm]

Thanks Andy for your reply. I tried to bleed again yesterday but still the problem exist. Do you think the LSVP is causing my brake problem? Some garage people are advising me to replace the booster or hydrovac (where the master cylinder was attached). Don't know if they named it right?

Pls advise!

More Thanks,
Chard

[andyverran]

Well, the pedal going to the floor would seem to me to indicate a lack of fluid pressure in the system. I can't really see how a lack of vacuum could be your problem, that would make the pedal hard, so I'd be a bit suspicious of the garage advice.

Does it have ABS?

Can you reproduce the long pedal in the drive for testing?

In which case I'd want to dream up a way to isolate the fluid flow to the rear and see if that stops it happeng (don't drive it on the road like that!). I don't think there are any rubber hoses to clamp before the LSPV so maybe try putting one on the feed pipe to LSPV and see...if no fault then your problem lays in the LSPV or the rear brakes...conversely of course if the fault is still there its not at the back....

Someone else might have a bettery plan mind!

No ABS....can you further explain this "Can you reproduce the long pedal in the drive for testing?". Sorry for my poor understanding.

You said in a previous post "I noticed the pedal drops intermittently"...that was what I was refering to.

[chardspm]

Actually I still use my surfie everyday. But has to maintain enough distance with car ahead of me, just in case it drops....I still have time to re-pedal.
