Servo Protection

[Griffinr]

Fitted a new servo and master cylinder yesterday and decided to give it a bit of protection. Went off down the scrapy and bought a plastic wheel arch liner, from an Astra I think, didn't take much notice. Well after a few cardboard templates and a bit of trial and error cutting and carving came up with this arrangement;


Works a treat.


Also protects the Bulkhead bearing. Second photo is on full lock.

Hi there

Great idea! I wondered if you could help me please. I need a new Brake Master Cylinder & Servo, which make did you use for the replacement parts and where did you buy them from....

If you could let me know, it would be greatly appreciated and get my S through the MOT

Thank you in advance for reading the above and look forward to hearing from you soon.

Kind regards

Lee

Have a look at this for the definitive information http://www.pistonheads.com/gassing/topic.asp?h=0&a...
Had a bit of luck with my servo, my nephew just happened to have one in the back of the garage which he was about to put out for the scrap man when I rescued it. The master cylinder I ordered from my local motor factors, gave him a few part numbers and he phoned his supplier who matched it to a Delphi unit, can’t remember the number will post later. Cost me £55 plus Vat. (does not come with the reservoir).
The brakes where and absolute pig to bleed, don’t know why for such a simple system.

Delphi master cylinder part number is LM80169

Hi all,another possible protection idea would be to make a fibre glass shoe which would be a perfect fit around the bottom of the servo.just lay up on top of release agent or even masking tape with several layers of 600 glass - remove and cut to desired shape.silicone in place.

Or maybe just a couple of coats of decent paint ?...

Not as satisfying as whittling a plastic liner though and won't protect the bulkhead bearing and the steering UJ.

Referring more to the rather OTT (IMHO) fibreglass ans silicone approach above

Most of these servo's have lasted well beyond their "design life" with nothing more than a quick slap of gloss black. I know yours is used regularly Rob but the majority are now fun days and Sundays cars so probably get nothing like the abuse they took in their earlier years, decent coat of paint should see them through another 20+ years no problem

My issue with trying to waterproof things ( improvised gaiters around steering uj's etc.) is that if it's not 100% water will get in and be held in, quite possibly making things worse.

Exactly.

I put a new steering UJ on my car a couple of years ago. I had to take it off to do the bottom joint last month. Now I don't know how it got in, but when I turned the joint over, there was quite a bit of water trapped inside the gaiter.

The UJ is still ok, but I didn't bother putting the gaiter back on (or to be more accurate, I forgot until the whole thing was back together, and couldn't be arsed taking it apart again).

I think that there is a possibility of doing more harm than good, trapping water between the servo and a shield for example. Extra paint or maybe rubberised stonechip would be better IMHO.
