Which Pressure Bleeder ?

[BenF]

I'm shortly going to be swapping out the callipers on my car, and as part of that I'm going to need to flush some new brake fluid through the system as the old fluid is due for replacement anyway.

With the different pressure bleeders, the usual problem is finding one with the right sort of cap to fit the Brake Fluid reservoir.

I've had a Gunson's Easybleed (  m http://www.machinemart.co.uk/shop/produ ... eeding+kit m  ) and various one-man and tyre-pressure based pressure bleeders but haven't got them working correctly on a Mk1 or Mk2 '2.

Many of the ones I can find require a small compressor - something I don't have.

The best I've found so far is a Sealey Power Bleeder :

With the universal adapter :

Which comes to £80.

But are there any other recommendations ?

I prefer the vacuum bleeder types , vary in price and quality

If you are swapping the calipers anyway, why not just install speedbleeders on each caliper. Flushing through is dead easy after fitting them and works when solo.

Hmm, not seen Speed Bleeders before - a quite clever idea.

Just reading up on them and what has been posted here and in other forums :

- They need to be used with care as a few people have snapped them off if overtightened
- They are a little 'taller' than normal bleed nipple
- In the USA they're available in standard or stainless versions - stainless being the one to probably go for given the salt on the roads in the winter.
- There's also talk of needing to refresh the threadlocking compound on the threads when you bleed them through to stop air being drawn in past the thread as you lift the brake pedal - has anyone had any issues with that?

Did you find someone selling them in the UK, or did you just order them in from the USA?

Ta - I didn't even know this sort of bleeder was available. Is there any danger of drawing air in past the thread of the bleed nipple with this sort of gear, leaving a few bubbles inside the calliper?

That one on eBay is surprisingly cheap - would you recommend that one, or a different one?

Theres a sealy one on amazon (they are supposed to be a good company ) and for the price worth a go i think ,

i read about putting grease around the nipple ,to stop air possibly being drawn past the threads ,
but that is not specific to using one of these ,i think thats for anytime you bleed brakes ?

I got the stainless ones from the States Ben. Not had an issue with the sealing compound yet, but you can order a bottle of it to re- apply as you need. I just find them really convenient. Not found an issue with the size of them.  Delivery was inside a week, both times I have ordered them.

[shnazzle]

On another forum I was told not to ever venture towards vacuum bleeders. Unfortunately I can't remember why or find the thread  s:( s:(  Very un-constructive, sorry.

As for the "compressor" you need... Some of them just tell you to use your spare tyre. Clever stuff. Works out especially well in the MR2 for where the master cylinder is in relation to the spare

It's because there's no thread on the master cylinder tank.

Thanks for the heads up on these, I am going to order some. Demon tweaks sell them now. Do you know what size the MR2 Roadster bleed nipple threads are?
thanks

I have used for years a small non return valve bleeder item number on eBay 151210721168 £5.49 absolutely brilliant bit of kit. Just connect to your bleed nipple and undo then pump away on pedal until all air has gone, allows air/brake fluid out and nothing back. You can stop at any point and top up resivoir until all fluid changed. When done tighten nipple and remove, job done.

[redarrow]

Dont forget if your bleeding the rear wheels
You take the handbrake off the calliper then re attach after it bleed.

The mr2 rear brakes are problematic if
You don't do it in the correct manner.

Thanks for the info, I've ordered one. It's the same as the bleed nipples above but you just use it inline, rather than replacing the nipple. And it's 1/4 price!

That's useful information, thank you. I'm replacing both rear calipers and fitting braided hoses at the same time... I didn't know about the handbrake issue
