C220 w204 brake pipe.

[whitefang]

Hi all.
Can I ask. Please.

On w204 c220 CDI.
On the passenger side (UK) rear , you have the jacking point. (Square / oblong shape).
Then a tray, if you remove the tray that's by that jack point, will there be brake pipes there.?

Thanks.

I couldn’t say tbh, have a look on YouTube, there’s a few brake pipe videos on there.

Hi toteimerced.
Only reason I asked this question..
On the BMW I remember that the brake lines run near the sill, including the fuel line.
I'm living in Ireland. MOT you call. We call NCT.
My w204 went into NCT yesterday, & when they lifted the car on the drive on scissor lift, they put a rubber / block of timber under the jacking points for another test.
The guy in the test centre (not like your UK any approved garage can do it , straight o r bent). Here its 1 company, with the odd test centre in each county.
But the guy must of missed judged were he put the rubber / timber blocks & it's smashed the under tray by passenger rear jack point & must of cut a breaker pipe.
After leaving the centre gates I noticed the peddle a bit spongy, I thought it was due to intense brake test.
I got few minutes down the road & brakes bearly stopping the car, then red lights on dash.
Brake pipe by the rear jack point got to be cut.
I haven't seen yet, i got the car on a transporter to my sister's house. & I won't be able to see / fix till Saturday, due to working. (Using wife car).
Pain in the ass these so called car testers / mechanics that only do a crap job or half job..

Thanks mate.

On a petrol W204 the two rear brake lines do run down the nearside under the tray and they are close to the edge. I see no reason why they would be different on a diesel.

Cool. Thanks for that 190.

On a 204 you'll find that MB brake lines are steel that corrodes - mine failed the MoT last January for this, where they go over the rear axle both sides. Garage had to cut the lines to both calipers then make and install Kunifer replacements, as to use originals they'd have had to get much longer lines, I think to the front of the car.
How old is your 204? Mine was close to 16 when this happened, if yours is that sort of age I'd recommend inspecting the rear brake lines from the caliper forward to where they disappear under the undertray before deciding how much needs replacing.

Thanks chrishazle.
Il have a look. Yeah, 131. (2013 ).

Thanks mate.

Did you go back to them about the pipe?

 

[Gazwould]

Yep close to the nearside edge.

Without a doubt they buggered it along with the undertray , but being steel brake pipes it was probably on it's way out .

 

[whitefang]

Thanks folk.
No,..didn't go back to them, I was about 20 minutes walk away & i had a friend coming with trailer & also the wife with shopping, so my 1st priority was get wife in a taxi & wait for friend.
What they going to do anyway...
Give the tester a warning ... Don't cut someone's brake pipes again or you get a written warning then bye bye.
To late for that after someone is dead in a crash.
I would like to go down there & smash the place to bits tho.
An eye for eye.

Thanks folk. Take it easy. & Please drive safe & mind your car.

Talk again in the future.

Thanks

That’s disgusting, lucky nobody was hurt, the least they can do is pay for the repair.

Sorry, but I would’ve turned around and driven back to the ramp and parked it!
I understand about your other half but surely she would understand??

Hi folk...it's me again.

The brakes.
W204 . C220 CDI . 2013 .

As you no from old post above.
My back passenger brake pipe (steel pipe
.not the hose) it burst.
I lost all pedal. & I put the car into safety in an Aldi car park.
I filled the empty resovour (under the bonnet) with new dot 4 fluid.
& Looked for leaks.
The part that was burst as been repaired with copper. (Not by me but a friend of mine & also sister partner, & the same guy that put the car onto a car transporter).

Today... (Saturday 19 Oct). We went down to sister place, jacked up the car ..bonnet & fluid resovour open & topped up.
Before we started bleeding, the pedal was none flat.

Dad opened the bleed nipple on rear driver side. Push to floor....hold while he do up... Off the pedal. ...again.. again x3.. he said nothing really came out.

Went to rear passenger & did the same... Nothing ..not much to no fluid. Kept on trying.
After doing this for say a hour he says only way to do it is ... Pipe onto bleed nipple...
Still nothing. Time as ran out.

I'm on way home in wife's car.

Can I ask....
Is there a procedure for a bleed on the complete system.?
The abs pump,.. I have a resovour that holds & supplies fluid. That's got full in.
Pipe from there to abs pump.. with 6 pipes on . 4 to brakes.. & which is meant (am I correct..) to supply power / pressure to the brakes.
Does the abs need bleeding.?

I see that there was different letters by the pipe on the pump. Can't recall what they are now.

We've / he's done millions of brakes... No problem...
Any help be great.

Thank you.

Did the NCT tester cause the damage or did the pipe burst because of corrosion ?
Sounds like you have an air lock in the system so try bleeding the system again from the furthest wheel from the master cylinder, prob offside rear and work your way round the system.
If that doesn’t work you may need to bleed the system under pressure from an external source.

Hi folk.

I'm reading this ...

The procedure is to add fluid, attach the bleeder to the top of the reservoir cap, and pump up the bleeder bottle to about 15-20 psi using the hand pump. This will pressurize the system. Check to make sure that there are no leaks around the bleeder or where it attaches to the top of the master cylinder reservoir.

Is that the only way.?
& the way we was doing it ... (The old school way.. open screw foot down .. tighten up foot off. X3 - 5 times job done... Or not on the w204).

Thanks again.

I changed the fluid on my 2014 e250 last year, did the conventional method of pump and release and it bled perfectly well.
You have trapped air in your system so have to force it out with the method you linked in your last post.

Did you have the engine running when you tried to bleed the brakes?

 

[whitefang]

Hi Geoff us.
I must of replied to myself at same time as you replied.
A friend changed the pipe before I got there, he said there was damage done to the undertray, from what he couldn't say or even an idea.
The brake pipe... Yes was a tester fault. But also said & showed me the piece of pipe that he changed & it was corroded. So the tester would of hit the brake pedal hard to test & the pipe give. A mechanic or a tester would of or should of known that the pedal is spongy & for them to test the car on the lift twice, then the tester had an idea something went wrong.
After me taking the car out of testing grounds & stopping at a roundabout & the brake pipe finally burst. Should I thank the tester for making the pipe weep, if I'd been on a motorway & hit the brakes they'd of burst along with my body in the pile up.
It's now being a nightmare to bleed.
& As I say above, I've been helping my dad since I was young, & he's never failed.
So he's like a demon at the moment.
& I'm not impressed with mercedes for building a car with junk pipes. Mercedes... not a cheap brand motor.

Thanks geoffus

 

[whitefang]

Yes mate, engine running.

So you think the abs pump don't need bleeding. ?
I've looked over the internet & on this site & folk are having problems.
Dad was saying on his w210 e300 d. 1997. He replaced 2 pipes from the wheel to abs pump, & had to bleed the pump somehow but I forget what he said.
& Usually abs pumps don't need bleeding, can be a be itch but do work after awhile. This w204 my car is not taking it.

Thanks geoffus.

 

[whitefang]

Sorry geoffus, yes, I'm looking at 1 of those bleed kit pump tools on Amazon now. Meant to say in last reply.

Cool.

 

[geoffus]

I don’t think your model needs anything special to bleed the ABS pump, I have an iCarsoft MB2 and that has an ABS function on it, never used it but I guess it opens all the valves to allow the air through.
Good news your tester found the weakness in the brake pipe and didn’t cause damage on the lift, the loss of braking during an emergency stop could be terrifying.
