Perentie Brake Boosters
« on: March 23, 2016, 11:39:05 AM »
Some help to clear some confusion and get this right please.

Here is some info from Wayne who is doing work on 49-149 FFR 4x4, restoring to all original parts.

quote:

[Since the FFR was rebuilt using a County Booster] I rung around to try and chase up a second hand brake Perentie booster - to see what sort of money they are worth, as i was quoted $375 for a rebuild [of the County booster] out of Bxxxxx Queanbeyan.

When I spoke to Triumph Rover in SA they said they had a few Perenties to wreck but their boosters sold like gold, they're highly on demand.

Then I spoke to KLR, who said he just gets them rebuilt and... [cost] maybe $400.

Then I found Landybitz on ebay who had a new L/R OEM replacement for $275. On closer inspection it is the original OEM for L/R County. Already having a L/R OEM County booster here, and knowing it works, why spend $400 when OEM is $275 new out of the box....doesn't make sense.

So then I tried ringing around to various brake specialist who claim they repair boosters.

Upon discussion they all state they send it to Sydney, they don't do it in house, nor do they give you the name of the company who do the brake booster service....

[After] more Google searching I found this company in Sydney called "Mako", wholesalers and repairers of boosters plus lots of other automotive stuff. When I spoke to the service guy Tony, he stated that they have only done (2) two of those Perentie boosters over many many years and that they are a very rare booster indeed (number PBR VH516 according to AULRO) so for total a rebuild $335 plus freight.

Total rebuild involves fully stripped, sand blasted, all new internals, primed, epoxy coated, factory finish as new. Then he sent me a email to confirm the price which finally made sense why these boosters where more expensive than the L/R OEM County ones.

        1/ These boosters where exclusively designed and built here in Australia opposed to UK L/R who out source for many parts offshore
       2/ These boosters where a dual diaphram booster not you average single diaphram booster, most handy when towing and heavy duty load application especially in 4WD hill climbs/descents.

...conclusion.....money well worth spent.

unquote

For starters, checking the part numbers PBR VH516 as per AULRO and PBR VH524.

The RPS 4x4 does say VH524 aka AYG2797.

Maybe thats the mix up - is the dual diaphram unit PBR VH516 the correct part for the 6x6 perhaps?

My Perentie 6x6 RPS (02209) specifies: PBR part No.: VH516 or Land Rover Part No.: AYG2669. 

The AULRO post on boosters has been updated to indicate the source of the information.  http://www.aulro.com/afvb/coil-sprung-military-land-rovers/226018-perentie-milspec-110-isuzu-parts-accessories-thread.html#post2493379

VH516 is still the correct 6x6 one with discs all round. Even the RFSV uses the same one as the drum braked models.

Just to add to the confusion I have just removed the brake booster assembly etc off my 1988 FFR the numbers on the booster are VH2519, I have been in touch with Mako I await an answer cheers Dennis
LOL Tony (Mako) rang me and said the number I gave him is part of the kit, I looked really hard and found the numbers VH524

A good save from Facebook of some chat this morning on the subject of Brake Booster and Vacuum line fault finding. Very interesting because I haven't had any problems with a booster. Definitely worth archiving here.

LR Perentie Owners group 29may2019 on Fbook.

James C.
Has anyone had to plumb in a diesel Vacuum tank after adding a turbo?

After adding a turbo I've been having strange brake booster behaviour. If I hit the brakes hard I have no problems but with prolonged gentle braking I lose booster pressure as the revs drop down to idle. I'm confident I don't have any leaks.

Russell F.
The vacuum pump is part of the alternator. I suspect that you have a leak in the Center Diff Lock vacuum piping - probably broken or melted as part of your turbo install.

James C.
I'm not having any center diff lock actuation issues so far.
I'll double check that hose though.

Russell F.
Thatís still where Iíd look first. If all seems ok then test your vacuum pump.

--------------

Dave F.
Most likely you've bumped off the fitting under the aircleaner that feeds the Center Diff Lock switch.

James C.
Centre Diff Lock has no issues engaging at the moment.

Dave F.
The Centre Diff Lock actuates easily.. it may only be fractured.

James C.
I'll double check under the air filter anyway.

Dave F.
I've also seen a fracture in the pipe at the brazing points cause it.

--------------

Rick C.
Same symptoms as mine had. My check valve on my booster was stuffed and so was the O ring on the CDL actuator causing oil to be sucked up the vac lines and somehow deposited in the brake booster, causing the diaphragm to fail.

It was fine as you say braking gently, but if you needed to brake harder, the pedal would go rock hard and have no vac assist. It appeared to be relative to engine revs too.

James C.
My symptoms are the opposite of yours. Hard braking I have normal booster vac assist. Gentle braking I gradually loose booster vacuum.

Rick C.
Mine did that as the problem started to develop. I would encourage you to check the lines for oil in any case.

James C.
Thanks Rick I will do that.

----------------

Chay G.
They use a double diaphragm in the booster, sounds like the primary is cactus. Booster overhaul kit to fix... If you're very mechanically competent, you can get the parts if you dig hard enough, otherwise take it to a specialist.

I can't relate to any of those problems other than the lads at KLR told me my booster needed looking at, so I took it off and sent to Mako in Sydney, very prompt service all back together cheers Dennis
