[diesel_mercedes] That " Sinking Feeling "

 

O.K. so it's been bugger-all hot here , over 103° F here every afternoon so I finally decided to enjoy a bit of R-12 induced air conditioning , my Klima II seems to work pretty well and God knows , my trusty Mercedes Diesel Sports Coupe goes _much_
faster and handles far better than my old , slow , noisy and hot Shop Truck does .

As I was waiting for a traffic light in the blistering heat I noticed the brake pedal begin to sink ever so slowly about 1/2" ~ this is a very bad thing indeed and means the master cylinder is failing , the internal rubber cups have begun to fail , allowing pressure to pass them instead of the pressure causing the cups lip seal edges to hold firmly .

From experience  I know an ATE (OEM brand) Master cylinder retails at close to $250 and the good guy price is $130 ~ $150 so I headed off to Rock Auto where I found a Centric branded one for $60.79 ~ this equals FREE FREIGHT in addition to lower co$t so I added in the two front brake cylinders my old Chevy (drum brake) Shop Truck needs along with a new rear brake hose for the truck just because I didn't like the way it looked last time I was underneath it doing routine Mtce.

In the end my total Rock Auto order came to $103.89 and I'll do the labor my ownself
including bleeding the whole system using the brake bleeder I've mentioned here before ~

Le$$ $ than the master cylinder alone much less than the co$t of having some Shop Boob touch my Mercedes and spilling brake fluid on the paint , not bleeding it to my picky-assed satisfaction , leaving grime on the seat , grease on the steering wheel etc.

Just another day in Paradise =8-) .

RE: Re: [diesel_mercedes] exhaust & turbo repair today

 

Thanx , Rob ;


I've been dragging my feet on this job for several years , you may recall my '84 Sports Coupe came to me with (among other maladies) a bound up turbo I was able to coax back to life by dribbling Marvel Mystery Oil on the oil feed pipe whilst hand rotating the dragging impeller ~ in time I bought a cheap used turbo  in Pick-A-Part (and am still kicking myself for not buying the freshly rebuilt one I spotted on a wreck in P-A-P one week before buying my Coupe that would need it) , it's working but I have sluggish off idle performance and continual if reduced smoking that covers the Cove with diesel smoot so I think installing one of Kent's kits as I like the idea of larger thrust area...

It spools up pretty quick now, so even around town it has much more pep, even w/ the AC on MAX. It seems like my impeller has been dragging all these years, robbing needed power.

If you don't want to rebuild yourself, Turbo City in Orange, CA will do it for you for a couple hundred bucks.
