Ill put it down to experience

I had done the other side wrong too, so have just swapped that around. The pads have made slight wear marks on my discs, but im sure they wont be too damaged. Also caliper has a little less paint but i shall repaint them as and when.

Rubbishy picture, but here it is sorted

Right, new problem

Got round to bleeding the system. I read the order from the Haynes manual. (RR/LR/RF/LF) So set about doing it.

Now as i understand it, after building up pressure by pumping the pedal a little i should open the bleed nipple and then the fluid will run out down the tube.
Then keeping the pedal pumped the fluid continues to run out. With bubbles in it.

Now i am under the knowledge that all these bubbles need to be gone Whilst keeping the reseviour topped up.

Done that but i have used 1 LITRE of brake fluid trying to bleed my right rear brake Simply because there is little bubbles constantly -



And then every now and then a bigger bubble -



Am i doing something wrong in having used a litre for one brake and the bubbles getting no less?


Sorry if thats essay-ish. Thanks for reading and thanks for help.

Marc

the fluid needs to be clear of ALL bubbles mate.me and a mate did the same on his clio and used about 2 1/2 litres of fluid.
just to clarify,you are pressing the pedal down with the bleed nipple open then tightening it up with the pedal down,then bringing the pedal up and repeating? And are ALL the nipples tight on the other calipers?

EDIT someone will correct me if wrong but you can re use the fluid i think

I was just letting my helper press the pedal up and down while the nipple was open

All other nipples are tight.
Im not re-using the fluid as it was rather dirty

yeah you see if you do that then the fluid is pushed out when the pedal is pushed down the when brought back up with the nipple open its sucking air back in thru it or the fluid with bubbles in it from the bottle in the kit.press pedal down to get fluid out then tighten as those kits still let air in.infact id fuck the kit off as they aint all that

I got rid of the square bottle thing and just left the pipe hanging into the pop bottle i decided to use.

I thought it would be ok because the fluid didnt appear to move back down when the pedal was lifted up

youre obviously still getting air in there though so id do as i posted above.itll work i promise you mate.and youve gotta remember youve done the front set up and rear hoses so there will be a lot of air in there.good luck but it will work if you press down,then tighten,then relaese pedal,then open nipple,the press down and so on etc.

Yes, start at the furthest one away, rear pass, and work closer.

When i did mine i got my mate to pump the pedal and another to keep filling with the brake fluid.

Also how are you bleading it? I've not read all the pages so if you've said it before quote it for me or describe it.

think your trying to hard to bleed it

try in the order you have

1. pump it 3 times with nipple open with pedal still down close nipple.
2. Then pedal down, open nipple (so pedal goes to floor) close nipple
3. Repeat step 2 twice more.
4. try it down the road
5. if need be repeat step 2 a couple more times after a couple of mile drive




If you still have a shit pedal try the pedal with the handbrake on one click, if its better then rear shoes needs adjusting.

I used a milk bottle to hold all the fluid and i must have gone through 7L of brake fluid to make sure everything is 100% free of bubbles. They compress = Very bad

Nipple closed, get mate to pump pedal, hold down and open nipple. Fluid and bubbles should come out. Now leave it open and tell him to keep pumping for 5 time. Close the nipple and tell him to pump again till it goes hard, hold foot down and open nipple.

Do that as many times as needed to make sure the there is no more bubbles left.

When i was happy that mine was all good, i cleaned the nipple and checked later to see if there is any leaks anywhere. There wasn't so went for a drive and all was ok.

Me being me, i did it all again a week later. No bubbles came out. Better safe than sorry.

Make sure that the res doesn't run low as you'll have to start all again.

Hope that helps.

Oh i used 5.1 from Halfords.

i had 2 2.5L and had to buy more. But i was really making sure that there was no bubbles left.

Although you'll never be able to pour the 5L thing coz it's far to big and don't get it on the paint work. If you do, was it off ASAP.

I hadnt quite thought about pouring it Bugger.

I got some in my eye the other day whilst trying to undo the brake hose First reaction was to get out from under the car by grabbing the bumper and sliding out.

Second reaction was shouting FUCK as i had brake fluid on my hands So thought sod the eye and washed the car down

dont get too hung up on bubbles. sometimes you can induce bubbles in the pipe if; a. the pipe isnt a tight fit on the nipple, b. if you slacken the nipple to much and it goes loose in the thread.

Just go methodically around each wheel doing it as described then test and road test!
