Excellent videos chap! Proper information! 👌🏽🙏🏽

[@jackkallemdjian3945]

Thanks for this info really interesting

[@introcar]

Glad you liked it, do let us know if you have any other ideas for technical videos for Matt to focus on :)

[@jackkallemdjian3945]

Matt can you do a talk on the camshaft issue on the push rod V8

[@nkelly.9]

Good stuff,
although the RR363 is hygroscopic, not hydroscopic.
a hydroscope is a device used to observe objects below the water ;)

[@introcar]

Thanks for the feedback.. will make the update to the blog and the video transcript! :)

brilliant

Thanx. Wasn't sure the Comma LHM was a good substitute for the Castrol version. I have a 1994 Brooklands.

[@introcar]

The key is to make sure that it is “LHM Plus”. Regular LHM was used on Jaguars and other brands but the “LHM plus “ is what is needed for your 1994 Brooklands. The Comma brand works just as well as the original Castrol.

Me too.

Great video - are there more videos or suggestions as we are having a difficult time knowing which way to go on the Azure we have lost brake pressure on? We watched the ronniesgarage videos on the old Rolls but not sure what applies on that with this Azure.

[@introcar]

If you have a problem with pressure, I would recommend that you have to start at the beginning and move through the system. Starting at the brake pumps and working down the system. It is definitely worth getting hold of a brake pressure gauge. You can depressurise the system, remove the pressure switches and fit the gauge in place of the switches. Then you can run the car and get a very clear picture of what is happening in the system. Makes it a lot easier to diagnose. the gauges need to be able to read up to 3000 psi and be for the compatible fluid.

[@garryhale9824]

We have removed the pumps, tested in a bucket of LHM+ mineral oil by attaching a hose to the discharge end and using a screwdriver to depress the push rod end. The pumps appear to be pumping. The pumps were very clean by the way. We purchased the o-ring kit to reinsert into the sleeves and reinstalled in the engine. Push rods were both approximately .500 above the push rod seats. However when turning the engine over, the pumps never "prime" and draw in fluid so to test pressure.
This begs the following questions:
1) Is there a priming step we are overlooking?
2) Does starving pumps imply clogged reservoir screens? Reservoirs are full by the way.
3) What else would stop fluid from being pulled into the pumps?
4) If there are screens in the reservoir, how do you get to those screens to inspect/clean?
Many thanks,

[@introcar]

The best way to prime the pumps is to disconnect the feed hose at the reservoir end and pour in some fluid directly so that it makes it's way all the way to the pump. Also you can loosen the high pressure pipe nut on the top of the pump but only a quarter turn and be ready to close it as soon as the pressure comes through.
you could also try pressurising the reservoir but be very careful doing this as you could split them if you put too much pressure.

I have cornish 76' which fluid should I use? The plate on the reservoir is faded out

[@introcar]

Hi Al,
If it is definitely from 76' then the right brake fluid to use is RR363 but to be sure you can send us your chassis number to double check

[@m114h]

@@introcar CRX 25466 here is the chassis# thank you very much for replying and helping

[@introcar]

@@m114h Not a problem. So yeah the correct brake fluid for your car is RR363

[@arabiandoctoroftheclassicc9475]

Hi dear thanks for ur info can i use the chf 11s fluid for rolls Royce silver shadow 1975 in brake system

[@introcar]

You cannot use the CHF fluid in the Shadow. CHF is a mineral based oil and will cause catastrophic failure to the hydraulic system on the Silver Shadow. The correct fluid to use is RR363 Brake fluid

[@mikeslambo]

1979 shadow can I use dot3 or dot4 please help

[@introcar]

Hi, we would not recommend either of those two. Really you should be using RR363, it will guarantee to lubricate the mechanical parts of your car better

[@425i]

Hi can you use Dot 5 silicon fluid instead of the RR363?

[@introcar]

Hi,
We have no experience with silicon brake fluid so would not recommend using anything other than the Castrol RR363

[@redez-ik5xz]

I use the dollar store brand
