I am trying to flush the brake fluid, after cracking a hard line, fixing it, installed braided hoses, new discs and pads, and I have also had my front Brembo's refurbished.

I have been trying to bleed the brakes using one of these kits http://www.ebay.co.uk/itm/Hand-Held-...IAAOSwLVZViAo6

however no brake fluid is coming out. I've already taken the master cylinder off and bled that, I'm certain there is no air on it.

Has anybody encountered a similar problem?

 

maybe a silly question but do you have the callipers on the correct side, i.e. bleed nipples facing up?

 

definitley the right way up

 

How many times have you tried? Does air come out?

 

Haha I was about to say this. I did it about 10 years back and it had the garage baffled for a while

 

Bleed nipples blocked with sh*te ?

 

Thanks for the replies, felt like setting fire to the car earlier, managed to get fluid to the caliper by pumping the pedal at least 30 times, however on tightening the bleed nipple, I noticed it was just spinning, I removed it and there was a coil of metal above the threaded portion of the the nipple.

I've just had the calipers refurbished and the powder coat is already breaking off where the nipple sits, its not a flat surface.

Now the caliper is leaking brake fluid over the fresh powder coat. I'm asssming the threads in the caliper have broken off.

There was also a sliver of metal in the caliper.

The master cylinder will probably empty itself overnight, so I'm back to square one, and I'm not sure if the caliper can be fixed.

Could i tap the caliper and insert a new nipple? Although Im not sure if a tap will have be able to create a new thread.

Could somebody please advise me which size tap I need and what is the next sized nipple I could fit?

Or would Quicksteel be strong enough to use a tap on and create new threads?

 

You could helicoil it. If it was me I'd send it back

 

what he said. if you've just handed over some notes to someone to refurb...it doesn't sound like they've done a very good job...

 

As above sounds like they have destroyed the threads, probably blocked the holes with powdered paint hence why they wont bleed, id be sending them back for them to fix there problems.

 

The thread needs to be helicoiled to go back to the original thread of M10x1mm.

We can fix them for you if you want to send it down.

Swarf in the calipers must be cleaned out , it will move about inside the calipers and will get under the seal and start leaking.

Even when we fix a bleed nipple thread , we split the caliper in half , remove the pistons and seals , repair the thread , thoroughly clean out the caliper , polish the pistons and chemically clean the seals , so we know its done right.

We fix threads for £30 each.

Thanks for the reply Ian, is the price £30 inclusing delivery back?
Thanks

 

No sorry , £10 delivery back to you

Cheers Ian

 

Took the caliper off today, to make matters worse one of the helicoils in the bolt holes has started to come out!

The bolts werent even torqued up, just hand tight

 

I can change the helicoil that's coming out foc if you're sending them in , it's easy enough to do that , for peace of mind send them both in and I'll check them over for you
Cheers Ian
