Installing the rear brake pad

[jimmy47785]

Greetings, everyone.
I need guidance on how to prevent the occurrence of friction between one of my rear brake pads and its corresponding disc. Yesterday, while stuck in slow-moving traffic, I suddenly became aware of a high-pitched noise coming from the back wheel, which seemed to be connected to its rotation.

A few hours ago, I elevated the vehicle, manually spun the wheel, and saw the brake pad making contact with the disc and causing visible abrasions as it moved. I hypothesise that when the disc undergoes heating and subsequently expands, the level of binding will intensify. Presumably, there exists a device for regulating the gap between the brake pad and the disc, however I lack knowledge on its nature.

While I cannot confirm its relevance, the shock absorber on this wheel was changed half a year ago.
The vehicle in question is a 22-year-old C220 Cdi Sports Coupe with a mileage over 271,000 miles. Despite its age, it remains dependable and incurs an annual cost of less than £800, inclusive of maintenance expenses.

Do you have any suggestions or thoughts?
Thank you.

Perhaps a malfunctioning calliper piston? Any garage should be able to diagnose the issue without difficulty.

[jimmy47785]

Thank you for that.
If we assume that the issue is a stuck calliper, do you have any estimate on the duration it would take for a garage to rectify the problem? I'm attempting to prevent being deceived or defrauded.

The cost of a new aftermarket rear brake calliper is around £40, and it would take roughly 1-1.5 hours of work at a general garage to install it. Additionally, I would replace the brake line, which would cost around £10. This price should include the 1-1.5 hours of effort.
I anticipate a payment of less than £150.

Have you attempted a series of forceful deceleration manoeuvres while travelling at high velocity? If you want to do so, ensure your safety by maintaining constant vigilance via your rearview mirror and avoiding a full cessation of movement.

I am curious about the level of similarity between the rear brakes of a 203 model and a 204 model. Recently, I had a very similar issue with the rear brakes of my 2008 S204 C220. It was discovered that the rear nearside calliper was entirely damaged, which was evident when I retrieved my vehicle and saw the calliper and disc. The cost of replacing the rear pads, 2 discs, calliper, wear sensor (all Pagid) and doing a brake fluid change at F1 Autocentres Ashford was far more than £150, amounting to an additional £500. Their pricing system incorporates menu pricing, eliminating the need for a separate labour fee on the invoice. The set of pads and the 2 discs were priced at £91.50 apiece, totaling £274.50. The calliper cost £180.40, the wear sensor cost £66, and the brake fluid replacement cost £33.33. All prices are subject to the additional 20% VAT. Receiving an unpleasant phone call was unexpected, since I was anticipating an issue with the front brake pads costing about £150. I was aware of the presence of wear sensors on both sides of the front brakes, but I was unaware that there is also a wear sensor on the rear NS (but not the OS!). The front brake pads and discs were replaced 8 years and 50,000 miles ago. This is how I discovered that I had wear sensors on both sides, even though my vehicle identification number (VIN) indicates that I should only have one on one side. The technician found two sensors, so they had to use an old one to complete the repair. Fortunately, the fronts were undamaged, and the brake pads still have an ample amount of material - a relief indeed!

On Friday, two days prior to my awareness of the problem, I travelled around 139 miles to Kettering and had many instances of abrupt braking throughout the route. The braking was typical.

[jimmy47785]

Indeed, that is correct!
Due to a momentary interruption on my vehicle radio that happened to coincide with very sluggish traffic, I managed to perceive the faint screech emanating from the rear offside. I may have detected my problem before it had any effect on the CD. However, considering my age of 22 years and mileage of 271,000, I must exercise caution in determining if a repair is really worthwhile.

What is the price of replacing the automobile in comparison to the cost of repairing it?

[jimmy47785]

Your question prompted me to further contemplate the advantages and disadvantages of a repair.
From a financial perspective, the value of my automobile is negligible. However, acquiring a similarly dependable replacement would need an expenditure of at least £5k (not considering a direct replacement). Moreover, this would result in an instant decrease in value due to depreciation. Given that I meticulously recorded the expenses of my previous vehicle and its current value is negligible, I am immune to the impact of depreciation. Under what circumstances would it be logical for me to cover the costs of several hundred pounds for repairs instead of immediately paying £5,000 for a new car?

I believe that has a certain degree of coherence.

In my opinion, my experience demonstrates the rationality of exploring several options before making a decision. The independent store closest to me is located very far away, however the F1 store is nearby and easily accessible.

[ML350_Colin]

You have misconstrued my statement. Locate a suitable location where you can drive at a speed of 70 miles per hour and use maximum force on the brake pedal, without exceeding your comfort level. Repeat this action. Determine whether that has an impact.

Are you referring to a discrepancy in the functionality of the calliper in order to release the binding? I have made a reservation for it, since Christmas is approaching and I need the automobile. Thank you.
