(URGENT HELP REQUIRED) Brake shoes and pads replaced, now super spongy

[shadowbroker]

Hi folks,

Can anyone help me please.

I got a new T2 a little while ago (2000 2.7TDi LWB auto) to replace my older one.

Yesterday , i did work on my brake system as the shoes and pads where down to nearly nil, and the calliper boots were a bit duff.

STUPIDLY THOUGH, when i removed the brake hose from the front callipers, i forgot to friggin clamp or seal the pipes. so lots pretty much everything.

......anyway, fixed the callipers, replaced shoes, pads, ect. bled the system as you do.

BUT, the brakes are dangerously spongy, even on a roll and brake peddle down full it takes a few feet to stop (thats just on an idle roll) also have the ABS warning light. have bled the system and cant seem to get anymore air out of it, where else is air hiding if not in the underside?

I would take to a garage for a quick solution, but i literally cant drive it now.

:bow:bow:bowCan someone please please please pretty please help me...:bow:bow:bow

I always place a plastic bag under the fluid cap, then nothing runs out.

Anyhow, there is a load sensing valve on some Terranos, this has a bleed nipple on it.
If yours has one, then it is over the rear axle, found by seeing a large coil spring, about 25 mm diameter.

Thank you

Thank you for your quick reply. Looking online, I think by not clamping the front pipes and loosing so much fluid I may have gotten lots of air in the master cylinder perhaps, so guess I now need to see a way to remove the air from it.

Take some time to read this post...

It includes ABS trapped air... and also Solarmans alternative bleeding method.

Hope it helps..

best regards,

Ha! I think I put my calipers on the wrong way round. Just noticed I have my bleed nips at the bottom notate top. Good lord I'm am ass

Apart from bleeding, if it's the same as mine the auto adjuster will take hundreds of pedal pressed to firm Up and make the handbrake better, mine is still improving now from seeing rick! :lol

I removed mine for that exact reason & now my brakes are spot on :thumbs

On a serious note to you & everybody else !

If you don't know how to do your brakes no matter how simple it may seem

ALWAYS get somebody that DOES know what there doing to do them as they are the most important item as far as safety goes for you & everybody else around you :thumbs

Have been swapped side to side

In the words of Del Boy...

What a plonker... lol
:lol:lol

I like your idea of having a drain at the bottom, to drain out any water....:doh

Looks like you'll be up and running soon...:thumb2

 

[AlexD333]

I think you've just done a me... :lol

Also another fine reason why you should take step my step pics with a smart phone or similar :thumb2

 

[shadowbroker]

oops

Done many times for lots of folk... Would be my own I bugger up with wouldn't it. I'm a silly tw@t. Seems much better now I have swapped them. Bleed properly again tomorrow.

Everyone feel free to give me a slap if you see me about.

 

[Sweety]

Calipers need to come off & swapped over to their correct sides then you'll be able to bleed the air out of them:thumb2 I normally clamp the flexy pipes to stop fluid draining out or air getting in further which helps to cut down the time bleeding them as I hate working brakes:doh

 

[firebobby]

When I changed my discs and pads, I didn't remove the flex hose from the calipers. Did you do that to sort out the rubber boots.

 

[shadowbroker]

I did, I more or less have it fixed now. But still have am ABS fault for some reason, even though it seems to be working as it should

 

[jims-terrano]

Inspect the abs sensor wiring on the nsf, for some reason the wires break on the inside of the cable usually where the metal clamp holds the cable. Can usually repair the cable but tape it up well.

 

[shadowbroker]

Thank you, will look at the line tomorrow. Just a wire or so inside the rubber covering?
