Hydraulic power head brake booster on my 1990 villa

Hya all, can anyone help, I'm trying to locate a new hydraulic brake booster, I have a slight leak of hydraulic oil coming out of the push rod that's attached to brake pedal underneath rubber dust preventer, does anyone know of where I could obtain a new one please, I know for a fact that no one in the UK would have one, also I need two brake light switches, and a brake pedal return spring, I've virtually finished got all the new calipers on and wheels and now able to move it back and forth 1st time in about 9 years, bit disappointed cause this has happened but will get over it, il attach some photos thanks kev

Sounds like the hydraulic brake booster has a seal that has deteriorated from age. Not a major leak. Cheaper (but a hassle to remove and replace) to have it rebuilt. Seals are pretty common size and cheap.

Kevin, yes take it off and rebuild it and you should be able to find someone that sells springs that would be close enough in tension. There must be some industrial or truck outfit that sells all types of coiled springs as we can here in Canada and US

Try Halfords or others Kev.

Yeah I would rather just get a new one though, I replaced the master cylinder last year new, but only just noticed a leak since I got it back running again, if anyone does know where I could by the complete new unit would be gratefull, perhaps someone over there sells recondition ones, but then their is usually a core charge, so I would have to pay a deposit and then send that back to USA before I get refund, so I then have extra shipping costs, i know they are nla at freightliner, but there must be a new one out there somewhere, I'm not to keen on stripping one down and rebuilding it,

Looks like you are going to do like we say over here:"Bite the bullet." Either way it is going to cost.

Kev, just a thought but why not email FTravel and explain were you live etc and if they can source it for you after you give them the build number of coach and .maybe vin#. Who knows they may be able to help. Do you have a # etc for the unit so maybe we can do some hunting around for you as well. Pierce is very good at that and I will see what I can find out. A good full side picture will help as well.
Cheers

When you wake up in the morning send this info on vin and pump to FT with a plea to them to see if they can help you at all with info on replacement unit.
If they cannot or will not  once I get back home from mexico next weekend I will see what I can do to help.

OK thanks, have been told that because it sutch. Small leak that it may be worth putting some of this stuff made by lucas which can stop most leaks in seals so it's worth giving it ago, it's amazing what products there are on the market, I remember bout three years go I had water coming from my car radiator, bought one very tiny bottle of stop leak and it hasn't leaked since, prob 50,000 miles

But its always handy to know where I can get a replacement, cause one day I might be out on the road and it packs up completely, so will have  a spare, I like to keep a selection of necessary spares,

I checked and I have 2 used units not sure if they came off a v814 or v815 Oshkosh. I will try to send pictures

That looks like a 1996  ChevyP30 brake release pump. The pump pushes a piston/cable  to release the parking brake drum.

Ron, are you sure that number is correct as it looks to me to have a 1 between the 7 and 4
I have been doing a lot of searching on internet and not having luck. I did find a section on the FMCA site in May 2015 with some comments by Brett and Nighthalk
