rundell Posted August 31, 2008 Report Share Posted August 31, 2008 Just finished putting in new springs on the front of my ke55 and when i was going to bleed the brakes on the calipers i broke the vavle to undo to bleed the brakes :fuzz: Is it suppose to be done that way to unscrew the vavle on the caliper? i got another front caliper but has the same problem the valve wont unscrew :@ any help thanks Quote Link to comment Share on other sites More sharing options...
WinKE55 Posted August 31, 2008 Report Share Posted August 31, 2008 (edited) Haha, ask Jon and Trev. We all had fun doing that today hah. You need the bleeder nipple, this is needed to bleed the brakes. There is a few ways to do this but I will say the easier way. Take off the master cylinder cap, where you fill your brake fluid. You can either suck it all out with a brake fluid sucker or get a rag and soak up all the fluid. Once that is done clean up the inside with a clean rag and re-fill up with brand new brake fluid. Blue brake fluid might make seeing it easier. Get someone inside the car, start from the far left side of the vehicle. Tell them to pump the brakes, after about 10 seconds say Hold, or whatever command and get them to hold their foot up hardly against the brake pedal, you then undo the bleeder nipple, let the brake fluid out a bit then close it off. Repeat until you either see blue or the desired brake fluid colour or until there is no bubbles or air in the lines. (Depends if you re-fill with brand new brake fluid or just want to bleed with the normal brake fluid you have in your car) Then move over to the far right wheel, then the front left wheel, then the front right wheel. The bleeder nipples are sometimes hard to crack, and be sure not to round them off so a proper tool is to use the desired MM pipe spanner, though you can use a normal spanner but have more chance of rounding the nipple. Oh, HAVE FUN :fuzz: Edited August 31, 2008 by WinKE55 Quote Link to comment Share on other sites More sharing options...
Falken_KE30 Posted August 31, 2008 Report Share Posted August 31, 2008 dunno if you read right Winkle, but he actually broke the bleeder valve on the caliper.. Mate, with your other caliper, try WD40 or something like that around the valve, and give it a crack and see what happens. if not ive used a flathead screw driver and a hammer to "chisel" it out... and yes you do use that valve to bleed brakes, Good luck mate Quote Link to comment Share on other sites More sharing options...
WinKE55 Posted August 31, 2008 Report Share Posted August 31, 2008 Yeah I read that, but man he said he has another so may as well replace it. Thought it might of made sense when I said the bleeder nipple is used so I would hope people would erm, use there common sense to realize he will either replace the caliper or attempt to get out the bleeder nipple.

Falken_KE30 Posted August 31, 2008 Report Share Posted August 31, 2008 i got another front caliper but has the same problem the valve wont unscrew :@ any help thanks And i offered him help on that..... Ive soaked the whole caliper in fuel over night, and also brake fluid before.. both have worked to undo it.. also WD40 works. Hope you get it sorted, they are a bugger of a thing to have snap on you... :fuzz: Quote Link to comment Share on other sites More sharing options...

I'd say its impossible to bleed the brakes without the nipples. If the above methods don't work and you're fairly skilled mechanically you could try slowly and carefully drilling out the spare front caliper bleed nipple with a drill bit slightly smaller in diameter than the nipple. Then try to unscrew/remove the remaining nipple metal without damaging the thread it goes into. If successful, you could just get another bleed nipple and replace the stuffed one.

rundell Posted August 31, 2008 Author Report Share Posted August 31, 2008 Yeh mates gonna take it into work and get out the snapped bleeder valve and put new one in but ill try soaking it in brake fluid or wd40 cheers for the helps. tryed to drive it without bleeding the brakes haha bad idea handbrake still worked tho :fuzz: Quote Link to comment Share on other sites More sharing options...
corollaart Posted September 1, 2008 Report Share Posted September 1, 2008 I don't no about soaking your caliper in fuel is such a great idea, fuel and rubber seals don't mix.If you can get a spray can of product called yield ,its in a gold can this stuff is the best i have seen.Spray around the bleeders and let soak for a few minutes usually works.Then if you get them out clean up threads put some nickel anti seize or similar on the treads never snap them off again.This what we use on dozer tracks and earth moving gear and you can always undo them. rob Quote Link to comment Share on other sites More sharing options...
rundell Posted September 1, 2008 Author Report Share Posted September 1, 2008 ahh might give them a whirl. Mate sed he has got the thread out and is cleaning the thread and putting in a new vavle so hopefully will be a lot easier and wont snap haha. Sucks everyhting was going right putting the springs in then the bloody bleeder valve had to snap so i can't drive my car :fuzz: thanks for all the help people have given Quote Link to comment Share on other sites More sharing options...
Falken_KE30 Posted September 1, 2008 Report Share Posted September 1, 2008 forgot to mention, when i soaked the caliper in the fuel, i had pulled the caliper right down, and just had what i needed to cover the valve in fuel, guess i should have said something haha yeah it sucks when you fix something, and then something else goes wrong haha Quote Link to comment Share on other sites More sharing options...
corollaart Posted September 1, 2008 Report Share Posted September 1, 2008 Also i wouldnt worry disconnecting the brake line to pull the strut out just carefully pull the clip off the strut and CAREFULLY hack saw one side of the retainer so you can bend it enough to get the brake line out.Then tie the caliper and brake lines up with a small bit of tie wire so you are not stretching any thing,then you can remove strut with out disconecting the brakes.This may be fround on but saves a lot of stuffing around. rob :fuzz: Quote Link to comment Share on other sites More sharing options...
