my brakes still not fixed really need the help now :(

[(NAS) starlet ep82]

Hi
As above some of u may know i'v jus done a big engine build including fittting HEL brake lines

So 1 month of trying to get brake pressure &. We have no brakes at all

Just fitted a 2nd hand master cylinder & brake servo & still have no brakes at all


Basically thres no brake pressure even after a few pumps
& when i start the car up pedal jus goes straight down to the floor

Thres no leaks anywhere on all the pipe connections etc

I'm actually losing the faith now

I have had the servo & master changed of a running car

Servo n master was changed from a ABS glanza

But my car is a GT ep82 with no ABS

We had the both rear calipers changed from another car n these calipers are in perfect working order

Wen we bleed the brakes its only the both rear brakes that have a more of a fizz rather than air bubbles

There are no leaks at all anywhere

As my friend presses the foot brake i can hear a air noise from near the master/servo is this normal?

Also as we press the brakes we can hear fluid at the rear brakes rushing around the pipes

& brake pedal gets hard after a few pumps then if i let go of it for 2 sec's it goes right down to the floor then

hi have'nt been on here in ages & not quite sure how to edit that format i copied n pasted my write up from another forum!

sorry for the layout guys

[richdog]

try an easi bleed kit!

[kavan-k]

You need to bleed them again laddy, fizzing, hearing fluid moving about the pipes and hearing air.... Defo bleed them again!

hi

we have already tried the easy bleeder

it's a actually my friends car parked at my unit (johnnygt) hes only signed up on tgtt.com

also we fitted hel braided lines all round & we had a look at MY ep82 & every line etc is fitted on correctly

we have bled them several times now

master cylinder & brake servo was changed too

we've spend nearly 3 weeks at my unit trying to get some brake pressure but its never gonna happen he's actually starting to hate the car now

this is very very strange tho as i've done brakes before on other cars without any problems

[(NAS) starlet ep82]

the only air we can hear is from near the servo vacuum hose it's also a new vacuum hose too

as we press the pedal down we can hear air coming from near the servo but this might be normal i think ???

really stuck with this now been well over weeks

surely someone must have come across the same problem this ??

what would be the next step ??

Seen a similar problem on a mate's car before, MS replaced after front brakes were binding. Then new MS and the pedal was dropping. Swapped another servo on and it works now. Servo you're using might be faulty or damaged

Thanks amjad for the info

I think we maybe gettin another servo n mastee cylinder from a running car lets hope this fixes it

Any more input on this guys anything else it can be ??

Not being funny, but you've checked you have enough brake fluid???

[Addymk2]

Again not being funny, you sure you've fitted the servo/master cylinder the right way around?

[(NAS) starlet ep82]

thanks guys everything was fitted the right way around

we changed the master cylinder again on HIS car & finally we have some brakes pedals bit down tho BUT also the rear passenger side caliper on his car is dragging the car back all a sudden & this is after we refitted the calipers back on the car &the new brake master cylinder

but yeah we have some brakes finally

& the caliper that is dragging back was totally fine last week help :/

cheers!
