Hello again,
Car was driving normally this morning, but after 3 miles brake pedal went spongy, less resistance and foot goes all the way down slowly (I never floored it completely though).
The braking power is ok and even (I can stomp on brakes with ABS kicking in), pumping the pedal with engine on brings it back firm as before, but goes spongy again soon after. No change in handbrake feeling/power.
Went another 7miles to mate's and did quick visual check: brake fluid is at its Max mark, no leaks around wheels whatsoever (did lots of pumping beforehand).
I think master cylinder seal is going - is it why the pedal turn so spongy all so sudden?
Is there any point in rebleeding brakes tonight, or should I bring it to garage instead immediately? Can a 206 HDi year 2000 be manually rebled btw ? (I got an EzBleed kit)
Did research on the Internet, here's a summary, given all my symptoms:
Quote:: |
1. The master cylinder is bypassing.
2. The callipers are bypassing.
You won't see a leak from the MC but you will from the callipers.
No fluid loss = internal seal in the master cylinder.
Fluid loss = leaking seal in one of the slave cylinders
|
Cheers for any comments to my highlighted questions above, otherwise this post could serve as a guide (and learning material), as there are so many different ways for brakes to fail..

Unless you have Peugeot Planet, you can't bleed the brakes.

You need to carefully look at every point on the brake system circuit as even a tiny amount of leakage will do this.
It might take a while for it to visibly drip down or reduce the fluid level in the reservoir, or it could be master cylinder as you say.
Do not continue driving the vehicle.

Mintex ones, no shims, since July 2012 - still good thick. This year started sticking to the caliper (squeeking) a bit on a hot day at low speeds.

Why, I thought it was to do with the ABS?

Only applies to the ABS system with ESP
Which the only 206 to have was the 180.

On non esp you only need PP to bleed the system when the ABS pump has been removed.
When on Peugeot planet you can turn the ABS pump on and off while bleeding to remove air from the pump itself.

Just checked Haynes manual, it says if dificulty is experienced in bleeding the braking curcuit, on models with ABS, this may be due to air being trapped in the ABS hydraulic system.
If this is the case then it should be taken to Peugeot, so the system can be bled using special equipment.

Just need to plug it into pp2000 and follow the instructions on the screen. Iv done it before, it just tells you what wheel to do then puts the pump on a few times.

It looks like my local garage won't take her until Thursday. Until then I'll need to investigate every inch of brake hoses myself tonight and tomorrow..
It's drizzle here in Bristol today - was hard to notice any obvious leaks due to wetness on the bottom of the car
