Just changed the oil in mine and my mates Bongo with my new Pela Pump. Great bit of kit akes the job so much easier.

Doesn't it just - gets it all out too

and you can bleed the brakes with one too!

I'm even thinking I might give myself an enema with mine tomorrow, if I'm bored

Don't envy you the job of cleaning that out!

Definitely don't Mike. They gave me one in the middle of the night before my big operation when I had meningitis at the age of ten. The memory still haunts me. You will have nightmeres.

My pela pump is at my place of work at the moment, it's connected up to the air conditioning of the shop bleeding the air out till a new compressor can be fitted

Best 30 odd quid i've ever spent!

Ok, i know it has many uses, but i can definitely say with no indecision at all that i've never considered sticking it up my bum.

I do worry about you Mike...

Me too, but I'm learning to stop worrying

On a technical point the Pela is desiged to suck not blow.... An enema requires positive pressure to instill a suitable liquid. Never suck when you should blow!

Seriously, don't try this at home

Dave - interested in how you use the pump to help bleed the brakes (as I'd like to do this myself). Do you connect the Pela to the farthest bleed point and use it to draw the fluid through? If so how do you connect it?

dave_aber · Post by **dave_aber** » Sun May 01, 2011 4:55 pm

Yes, just that - I used a short section of small bore silicon hose to connect the Pela pipe to the bleed nipple, pumped up a suitable vacuum, open the bleed nipple, and the vacuum should draw the fluid from reservoir to caliper and out. IIRC you should always do the furthest nipple first, then the next closest, etc.

I had tried back-bleeding using an easi-bleed kit (this was on my son's Toyota Starlet), but as I knew would happen when I wasn't looking the damn thing popped off the bleed nipple and sprayed brake fluid everywhere.

It was an inspired, and somewhat under pressure, moment I looked over at the pela pump and thought "Hmmm.... I wonder....". Worked a treat, and as you are sucking, not blowing (see above for the importance of this!) then the pipe is not likely to fall off!

Cheers Dave - sounds like a great idea, I'll be trying that myself shortly.

That is a seriously good tip. Does that mean all the old fashioned stuff about pumping the brake pedal is consigned to the dustbin of history also? If so, I think it's time I changed my brake fluid (I bought fluids and an eezi-bleed 4+ years ago to do it, but never did!).

I presume you need someone at the reservoir end topping up as the level drops, or can you do the job single-handed?

Also, how do you decide when you can stop bleeding each wheel - do you see an obvious change in colour/clarity, even through the silicon tube?

What about doing a quick factsheet on how to bleed/change brake fluid on the Bongo with a Pela pump, as more and more Bongo owners are buying and using them?

Top tip though

Pretty much yes to all your questions - you can 'keep up' at the reservoir end fairly easily, as it pulls the fluid through at a sensible rate. Gone indeed are the days of "DOWN, HOLD", tighten, "UP", slacken, "DOWN, HOLD", etc.

The silicone hose I used was pretty transparent, so I could see the air bubbles coming through, and then stopping. The fluid was pretty much the same colour though, I guess you'd just have to make a judgement call on that one.

Factsheet - not a bad idea. My Bongo is a 1997 model, so it's probably on 14 year old brake fluid. I'm planning on doing the ATF next time I'm home, so I could (should) probably do the brake fluid too.

The problem with Eezi-bleeds are that there never seem to be reservoir caps for Japanese models - probably because they tend to be rubber caps rather than screw-on plastic lids, so wouldn't hold the pressure anyway. You can still use an eezi-bleed, but you have to inject the fluid at the bleed nipple end. This leads to a problem as you need to syphon the fluid out at the reservoir as it comes through. More worrying is if you have no dust caps on your bleed nipples, you will probably push all manner of crap into the brake calipers. The old adage "dirt is death to hydraulic systems" comes to mind....
