[@tubthumper42]

Ayup there mike my top tipette is to take the entire brake tower out and change it all out on the bench loads easier.Atb Andy.

[@BritannicaRestorations]

This was not too bad - you should see the mess that is holding on the tower

[@SiCrewe]

Pro-tip: always put a smear of coppaslip/anti-seize around the ends of brake pipes after you work on them - being careful not to get any INSIDE the pipes. Everybody knows that brake *fittings* can be an arse to remove but often the fittings get rust-welded to the ends of the pipes and you're forced to mangle the pipes as you unscrew the fittings. A dab of coppaslip will prevent this and future-you will thank you for doing it. Coincidentally, I fitted a new master-cylinder to a 110 last weekend (amongst other brake repairs) for the MOT and BOTH the fittings on the top of the master-cylinder were rusted to the pipes, which resulted in the pipes shearing as I unscrewed the fittings... and forced me to replace the bloody pipes too, even though they were in decent condition. Even if you're using cunifer pipe, when the fittings go rusty it can cause them to seize onto the pipe so coppaslip is still a good idea. Also, you know that when you did that brake-test, the rear wheels were still turning, right? ;-)

[@gshort4707]

I agree rusted unions are a real pain. Red rubber grease is waterproof and brake fluid friendly so I smear that on my unions. No need to worry if a dob of it gets inside the pipe. You can get brass unions as well. I would be interested in Mikes view on using them. I assume they work well but manufacturers don't fit them due to cost?

[@BritannicaRestorations]

It has drum brakes and there is a pressure reducing valve in line - you do not want the rears to lock solid as it is light on the back end -- locked rears can spin the truck on wet roads ( go on ask me how I know that! lol!)

[@BritannicaRestorations]

Yes brass fittings are good, but hard to find - some of the pre made kits have them From experience, I only see them on Cunifer lines as there is less torque needed to seal the joint - on steel lines I think there could be a tendency to strip the threads

[@gshort4707]

@@BritannicaRestorations Car Builder Solutions (UK based) have a good selection of brass unions, both metric and imperial. They also do stainless steel, which I guess would work with steel lines.

Just done a master cylinder swap on a 300tdi, bad brakes, swapped pads and rear calipers as they were seized, discs ain't the best either, pedal gets sucked down on startup so hoping the new discs will sort it without a servo swap.

@@BritannicaRestorations Thought it was the M/C cos pedal was spongy even after bleeding, checked all hoses and all good. Vacuum pump creates decent vacuum and pedal is sucked down on startup, at least its only £45 for a new servo (one advantage of the UK and having a land rover supermarket down the road) discs are worn very unevenly anyway so could do with replacing, just a bit of a faf to fit.

Guys i am having problems with my Landy brakes. My front disc brakes are not releasing when i take my foot off the pedal. I have put brand new calipers and new hoses on both wheels. The brakes get so tight after about 10 minutes driving, that i have to stop to let the discs cool down before driving off again. There are no kinks in the hoses at all. Could there be a master cylinder problem? Appreciate any feed back please. Landy is almost 30 yrs old, and master cylinder is the original one. Thanks in advance Tony

[@BritannicaRestorations]

It could be the servo has been played with and the push rod adjusted too much - or a bad master - the fluid is not returning to the master cylinder

Just a bloke who hasn't ever done a brake master cylinder, only brake calipers and clutch master and slave cylinders. I am/was of the belief that all succeeding DOT brake fluids could be used on and mixed with a former type but had superior properties. Why would you use an older spec?

[@gazzafloss]

Can be used in a fully cleaned system I think, but mixed no...

[@COIcultist]

@@gazzafloss As far as I'm aware you only need to uprate a fluid i.e. from DOT 3 to 4 to 5.1 but specifically not DOT 5 which is a completely different silicone fluid. This would be bourne out by several websites. The problem is I used to moderate and write for a folding camper website and I wrote a piece on UK towing regulations. The amount of sites that got the law wrong including at one point Gov UK were unbelievable. Alas, Gov UK didn't provide a historical page to show its error. I have very little belief in websites. Look at these below: www.brakeandfrontend.com/brake-fluid-dot-3-4-5-5-1-faq/ rxmechanic.com/dot-3-vs-dot-4-vs-dot-5/ epicbleedsolutions.com/blogs/faq/whats-the-difference-between-dot-4-and-dot-5-1-brake-fluid# haynes.com/en-us/tips-tutorials/brake-fluid-types-explained Some of whom agree with me some don't two of whom list the dry boiling point of DOT3 fluid as 205 deg C or 250 deg C. One says "DOT 3 brake fluids are a petroleum/non-mineral based, non-silicone, and fully synthetic brake fluid designed for use in a wide range of clutch and brake applications." How can it be petroleum based yet non-mineral? Surely it can't be fully synthetic either if petroleum based? Once upon a time I might have believed Haynes who tell you can't mix any fluid but Haynes appear more interested in selling crap books rather than car mechanics and let's face it even many years ago we all knew. Assembly wasn't just a simple reversal of the above procedure!

[@gshort4707]

A quick search on UK eBay gives a litre of Comma Dot 3 £8.60, a litre of Dot 4 £7.99. I can't see the advantage of using Dot 3 unless Canadian or wholesale prices are different from UK. You can't mix Dot 5 with any other, but Dot 4 can be used instead/mixed with Dot 3.

[@BritannicaRestorations]

DOT3 is the most popular here for disc front, drum rear applications and sold in gallons but DOT4 is sold in litres, and as 80% of the old trucks I get here are over 25 years old DOT3 is ok for my use - there is only 10c difference in dry boiling point as far as I am aware - if they sold it in gallons I would buy it I agree do not mix DOT3/4 with 5
