Badly corroded brake lines

[James_Rover99]

I have just acquired a discotheque.The user's text is too short to be rewritten academically. Please provide a longer

I opted to have a comprehensive maintenance procedure conducted at the 112,000-mile mark in order to ensure the vehicle's overall condition and functionality.

Following the completion of the service

The following concerns;

The brake pipe located on the rear nearside of the vehicle is exhibiting signs of leakage and corrosion.

The coolant reservoir is completely depleted.

The power steering fluid level is low and requires replenishment.

I am inquiring about the appropriate valuation for the repair expenses associated with the brake pipe.

Are there any factors that might explain the complete absence of coolant, notwithstanding the absence of any visible signs of leakage upon first inspection? Are there any absence of warning indicators on the vehicle's dashboard?

The car in question is a 2016 Disco 4 3.0 SVD6 model with a comprehensive service history. It is acknowledged that owning such a vehicle entails greater expenses and potential issues.

I lack familiarity with D4s; but, in the event of complete depletion of radiator coolant, the engine would experience overheating and potential seizure if used continuously for more than a brief duration. It is quite probable that the header tank is depleted of its contents. The absence of a warning light does not necessarily indicate a malfunction, since the primary system may still be operating at full capacity and functioning well.
Are you aware of the most recent coolant replacement and the individual responsible for doing the task? Airlocks may be present in the system, which may initially provide the illusion of fullness. However, with further examination, it becomes evident that the level of the header tank decreases.

The rear brake pipes for a D4 vehicle seem to be rather inexpensive, with a price range of £15-20 plus VAT, when purchased as pre-shaped components packaged in a blue bag. The outcome will be contingent upon the particular pipe in question. Alternatively, it is justifiable for your garage to go for an in-house solution. If the vehicle has Cunifer pipe, it is likely that the pipe will have a longer lifespan compared to other components of the vehicle.

The installation of the new pipe will need a certain level of effort, as will the subsequent processes of cleansing and re-bleeding the system.
If a single pipe exhibits corrosion and leakage, it is opportune to conduct a comprehensive examination of the remaining brake pipes for signs of corrosion and assess the state of the brake flexi hoses. Subsequently, it is advisable to repair these components concurrently.
In terms of cost-effectiveness, doing a single cleaning and bleeding procedure for your brakes becomes advantageous in the long term. It is advisable to undertake these maintenance tasks promptly rather than waiting until brake failure occurs.

I am rather taken aback by the description provided, which states that the brake line is exhibiting signs of leakage and corrosion.

It would be reasonable to assume that the loss of brake functionality would occur if there were a brake fluid leak. Moreover, it would be prudent to question the reliability of an automotive repair facility that would permit the operation of a vehicle with compromised brake lines.

I concur wholeheartedly with the viewpoint expressed by @Iain SIII. The present moment presents an opportune occasion to organise and categorise all the brake lines. By using the use of cunifer, one may effectively avoid the need to repeat the aforementioned actions. Particularly when use protective measures such as waxoyl or similar substances. (However, it is important to anticipate the presence of MOT wording such as 'brake line covered with grease or other material'.) It may be inferred that the underlying quality of the subject matter is satisfactory.

Thank you for your response. The garage advised me to keep the vehicle in their care due to safety concerns. I was mentally ready for a negative outcome. I am seeking a reputable garage that can provide a recommendation for the use of cunifer.

Pipes available for purchase are offered in individual components (Britpart), although the kits seem to be constructed from mild steel, so presenting a same issue over time.

It is quite likely that cunifer will be used in your garage, since it has been a prevalent choice in contemporary garage construction. A whole roll of cunifer, also known as cupro-nickel due to its composition of 90% copper and 10% nickel, is priced at around £30. This pricing comparison reveals that purchasing the entire roll is a more cost-effective option than buying individual portions. The garage will engage in the process of cutting and flaring in order to get a proper fit. In terms of cost, replacing a single brake line typically incurs an hour's worth of work charges, in addition to the cost of the necessary components. The estimated time required for completing all tasks is around 4 to 6 hours. Depending on additional factors that may need attention, such as access and other related considerations. A reputable automotive repair facility would often provide an estimated duration and cost for their services, often based on a standardised reference known as "book time."

The topic under consideration is power steering. There is a possibility of a leak present, which may be conveniently refilled, followed by monitoring the fluid levels. Examine for the presence of liquid droplets under the surface. Typically, the occurrence of leaks is often seen at pipe junctions, which are consistently installed in locations that provide the greatest difficulty in accessibility. The compatibility of the D4 power steering system with 'stop leak' additives available for purchase remains uncertain. However, it is worth noting that if the issue lies with a hose, the efficacy of such additives would be limited, since they primarily target internal seals.

Likewise, ensure that the coolant is replenished and maintain vigilant monitoring of its levels. It is essential to use the appropriate antifreeze solution and adhere to the recommended combination %.

It has been suggested that the inclusion of the term 'fer' in Cunifer may be indicative of the presence of iron inside the alloy.

[KARlosfuentes]

Alternatively, might it be the case that they deliberately chose not to refer to them as 'Cuni' pipes?

Indeed, the chemical symbol Fe is often used to represent the element iron. However, it is worth noting that the term Cunifer (or even Kunifer) may have been used as a brand name or trademark in relation to this matter. The majority of the copper-nickel pipe now in circulation is not marketed under the specific trade name "Cunifer." This colloquial term is often used to refer to such pipes, akin to requesting a roll of sellotape and receiving adhesive-backed plastic instead. It is likely that those that use the name do so without obtaining proper authorization from the trademark owner.

In response to your query, I would like to provide a scholarly perspective.

[KARlosfuentes]

The subject matter is intriguing.

This alloy is often known as Kunifer, or alternatively referred to as Cupro-nickel. There is no reference to the presence of iron in any of the blurbs that I have come across.The 90/10% combination is often referenced in literature.

Copper (Cu) is a chemical element.
The chemical symbol Ni represents the element nickel.
The chemical symbol for the element iron is Fe.
