Car went down local garage today to get the brake system bled with new stuff

Now, I've got it back and its 100 times worse

Brake pedal nearly goes to floor and no bits at all

Need exact procedure how to bleed AP-4 pot calipers with a rear disc conversion

Please help and there's got to be something they haven't done or something has broke

Also, the servo tilts forward at the top when brake pedal is pressed, moves about 1/2 inch!!

 

are the calipers at the top a la 4x4 cossie???? if so you need to bleed them upright, so you'd need to undo the calipers and sort of support them on the disc (so the bleed nipple is uppermost) - then bleed it in that position!!

 

Kev, haven't a clue what you mean so went out and took a pic for ya LOL

 

Or, you taking about rear discs?

If so I think I know what you mean now...

 

Just claify though if ya can please... Might of mis-understood

 

if the servo is moving on its mountings that would increase pedal travel!!

 

was fine b4 fluid change though, btw u have a PM

 

when i bled my wilwoods and cozzie rear discs the pedal was crap.. but just using them brought the pedal right up and they are fine now!!!

maybe i was just lucky!!!

 

Right, I thought that you had the fours on the back!!! However, It still applies. The rear caliper is at the top and the bleed nipple is facing forwards(or backwards) and is not at the top so the air can sit higher than the nipple, therefore the pedal is always going to be spongy, thats why they need to be bled with the nipple at the top.
However it all depends on what you've done to the system as if you've only changed the fronts, then there should'nt really be air that far back!!

 

Aaaaaaaaaaaah, I just ran out and looked

The pic is of front calipers

Rears, the bleed nipple tilts backwards and yes the line DOES go in HIGHER than the nipple

But the guys said no air coming out, prob cos it can't get out!! LOL

Will get them to do it tomorrow, many MANY thanks

 

Is that those Monkeys at the garage 'Down the Road' from you??

Well, at least they are cheap!!

 

......... and you didn't take it to APT because..........................?





Ah, maybe you were worried you'd get the job done right first time!

 

Ł45 an hour or whatever, plus fuel and time

Whole day in reality and over Ł70 down

 

No, Richard, its because we wouldn't do it for a Fiver and a portion of Chips.

 

Maccy D's chips, or McCain's home fries cooked and brought with in a thermos flask?

 

Ah, but Ł40 per hour buys you someone that KNOWS that Bleed Nipples should be at the Highest point when Bleeding in order to remove the air and Load Proportioning Valves (if fitted) must be fully open. Also, that you should Bleed brakes starting at the furthest wheel from the Master Cylinder........

 

I know the furthest away bit, but I rekcon it's cos the rear line comes in higher than the bleed nipple

They good lads and this isn't the normal kind of car they work on

Not everyone has to go to a named company and spend more than they have too

 

That's very true.

You can go to an un-named company and spend more than you have to instead

 

Why would I havr to spend more? - they ain't gonna charge me for it
In all we agreed Ł20 would cover it, it's walking distance too

He dropped it off - said if ya can see what other's do with that set-up and we'll do it again tomorrow

At least I know it all fresh fluid LOL

 

That comment is kind of worrying...

Says to me that they aint got a clue and to ask someone who does (for free) and we will do it that way.

 

Well how many cars do you see with AP's up front and rear discs Ade?? not many in a normal gagarge.......

 

James, why didn't you just take it to APT?

 

at rich

now im awaiting the next installment ...

they say i cant have discs on the back

sorry james

 

As requested

 

Brakes are brakes. Rear discs all over the place.

Any mechanic should know his/her way round bleeding.

I'll call my sister James, she might know more than the monkeys you are using!
