...was trying to fix my brakes today, front ones no problem, rear ones are shit.
followed the step by step instructions in the cosworth manual but nothing realy happend on the rear ones.

when I press on the breakpedal i have pressure but when opening the rear brake bleed valves there's NO oil coming through

abs pump is running, i can hear it 'buzzing' as described in the cossie manual.

calipers are in very good condition and i fitted some brandnew hoses, oil is also brandnew

what can be the problem ?

thx in advance

 

have you bled them properly?

starting furthest from the servo working your way to the closest? lower the back end of the car if u can when doing the rears! does the handbrake work fine? can elimenate pads/calipers if so i think

 

ermmm... not realy

started with the front ones; right one first, secondly left one and worked my up too the rear ones, as discriped in the cosworth manual or i'm i that stupid to misunderstand the manual?

the handbrake works perfectly

 

lol this is taken from a website!

"This is the process of removing air bubbles from the brake system by pumping fluid through the lines. Air bubbles are bad because they compress when pressure is applied resulting in a low or spongy feeling pedal. The correct procedure for bleeding the brakes on most RWD vehicles is to start at the furthest wheel. Do the right rear then left rear brake, followed by the right front and left front brakes. "

was u in a rush

 

nope... i wasn't in a rush mate

damn me

now what? start all over again?

 

you need to do passenger side rear first

then drivers side rear

then passenger front

then drivers side front

abs pump should shoot fluid out on the back

 

vroooom ptssssh, right, thanks mate

CraigN, thanks mate, shall i just re-do it ? or any other suggestions?

 

Np buddy, glad to help. Mind your cossie will maybe be left hand drive so watch out what wheels furthest away?

 

yep, my cossie is a left hand drive one but it's the same way like your cars.

my abs pump sits on the left side of my car so i have to do the passenger side rear first, then drivers site rear, etc. etc...

 

aye, good man, let's know how it goes, mind if u can lower the rear of the car, then do that or even raise the front, helps

 

Just did mine last night. The rear pistons are a c*nt to get turned back in unless you got the right tool. Which of course I don't. Good luck with the bleeding.

 

turning in the rear pistons is death easy (even without the right tools)

you have to create your own tools which i did

will have a second go this afternoon

 

On the rear calipers , you need to bleed them different from the front , pump the pedal a few times to bring the ABS pump on , when it stops get someone to press the brake and hold it down , now open the bleed nipple on the caliper and it will pump out itself , you dont need to pump the pedal , just keep it down , it will bleed straight away.
