Fitment Notes
- Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
- This is a rear-axle caliper repair kit for ATE-specification brake systems with a 35mm piston bore. Confirm your caliper is ATE and the piston bore is 35mm before ordering — other manufacturers (Bendix, Girling, Teves variants) and other bore sizes will not fit.
- Covers a wide spread of Mercedes-Benz chassis (W114, W115, W116, W123, W124, W126, R107, R129) plus Opel Senator, Chevrolet Senator and Volvo 140/160/850 applications sharing the same rear caliper specification.
Installation / Use / Maintenance Tips
- Caliper repair kits must be fitted by a qualified brake technician — incorrect assembly can cause brake failure.
- Clean the caliper bore thoroughly and inspect for pitting, scoring or corrosion before reassembly; replace the caliper body if damaged.
- Lubricate new seals with the correct brake-assembly paste or clean brake fluid only — never use petroleum-based grease.
- Bleed the brake circuit fully after reassembly and check for leaks under pressure before road testing.
- Replace brake fluid with the correct DOT specification for the vehicle and check handbrake operation where the rear caliper incorporates the parking brake.
Common Questions
Will this rear caliper repair kit fit my Mercedes-Benz?
This part (CK38.0981) is listed for the fitments shown on this page. Confirm by matching the fitment details, verifying the caliper is ATE with a 35mm bore, and checking VIN/engine/chassis information where variants exist.
What OEM part numbers does this cross-reference?
Cross-reference numbers are listed in the OEM Reference Numbers section above. Match at least one to your original part before ordering.
Why are the OE numbers Opel and Saab if this fits Mercedes-Benz as well?
Caliper repair kits are grouped by caliper specification (manufacturer, bore size, position) rather than by a single vehicle OE number. The listed Opel and Saab part numbers are the primary cross-references; the same 35mm ATE rear caliper was also fitted to a wide range of Mercedes-Benz and Volvo platforms of the same era.
How do I confirm fitment if there are multiple variants?
Use VIN, engine code, and chassis/platform details and compare them to the fitment section above. If unsure, request fitment assistance before ordering.

Hydrating Serum That Leaves Skin Smooth and Plump
Size: 1 Fl Oz (Pack of 1)
This serum feels really hydrating and helps my skin look smoother and more refreshed. It absorbs nicely without feeling too heavy, and my skin feels softer and more moisturized after using it consistently.
I also like that it includes ceramides and vitamin B5, which help support the skin barrier while adding hydration. It layers well with other skincare products and works great for both day and night routines. Overall, a great affordable serum for keeping skin hydrated and healthy-looking!

Affordable and Lightweight Hyaluronic Acid Serum
Size: 1 Fl Oz (Pack of 1), Size: 1 Fl Oz (Pack of 1)
I absolutely love The Ordinary brand and own quite a few of their skincare products, so I was excited to add this hyaluronic acid serum to my routine. I use it after cleansing my face and before applying moisturizer, and it layers really nicely with the rest of my skincare. One of the things I appreciate most about this product is the packaging. The glass bottle feels high-quality, and the dropper makes application easy and convenient.
The serum itself is very lightweight, and a little bit goes a long way, so the bottle should last quite a while. It absorbs nicely into the skin without feeling greasy or sticky afterward. I also really appreciate the clean ingredients and the fact that there are no added perfumes or strong scents, which is important for my sensitive skin and overall preference for non-irritating skincare products.
As with most skincare products, I know it takes consistency and several months of use before you can truly judge long-term results and improvements in your skin. Because of that, I cannot fully speak yet on how effective it is overall, but so far I have been enjoying using it and have had no irritation or issues. For the affordable price point and quality ingredients, I think this is a great skincare product, and I plan to continue using it and update my review later on with long-term results.

The Ordinary Hyaluronic Acid 2% + B5 (with Ceramides)
Size: 1 Fl Oz (Pack of 1)
The Ordinary’s Hyaluronic Acid 2% + B5 with added ceramides is a hydration powerhouse that delivers noticeable moisture and placid comfort to dry, dehydrated, or combination skin. Hyaluronic acid draws water into the skin’s surface layers, helping skin feel plump, soft, and smooth, while vitamin B5 supports enhanced surface hydration and recovery.
Adding ceramides is a smart touch because they help reinforce the skin barrier, locking in moisture and preventing water loss throughout the day. The result is a formula that doesn’t just sit on the surface — it helps improve the skin’s resilience over time.
The texture is lightweight and gel-like, absorbing quickly without leaving a sticky or heavy feel, making it easy to layer under serums, moisturizers, and sunscreen. It works beautifully in both morning and evening routines.
After consistent use, many users notice better overall hydration, smoother fine lines caused by dryness, and a more comfortable complexion — especially during dry seasons or in air-conditioned environments.
Pros:
✔ Deep hydration that lasts
✔ Lightweight and fast-absorbing
✔ Great paired with other products (moisturizers / creams)
✔ Ceramides help support the skin barrier
Cons:
✖ Not a direct treatment for acne or pigmentation
✖ Effects build gradually with consistent use
Overall: A very effective and versatile hydrator that’s easy to use and works well for most skin types. Particularly great if you want lasting moisture and a smoother, healthier-feeling complexion.

Amazing product - instant smoothness
Size: 1 Fl Oz (Pack of 1)
I've only had this product for the last several days, but, so far, it's AMAZING. I've tried hyaluronic products before, because everyone says that you are supposed to for moisture, but, honestly, I was always underwhelmed. They were thin and did nothing. So, despite this one having great reviews, I was not really expecting anything, but the price was right.
But this product....although liquid and clear, it's got a slight thickness to it, and spreads on very smooth. You only need a little bit to cover your entire face. Despite the slight thickness, it's not gooey or sticky at all, and it dries incredibly fast. In fact, if you don't spread it around onto your face quickly enough, it's already drying. There is no real smell to it. And, as soon as it dries onto your face, your skin feels incredibly smooth. Maybe it wouldn't if you had a significant dry skin problem to begin with, but for regular, maturing skin, it leaves skin baby smooth. And it lasts all day, and my skin looks better.
I have very sensitive skin, and most things on my face eventually make my eyes water (even gentle facial moisturizers and sunscreens), but, so far, I haven't had an issue, and, because it's been a few days already, maybe I won't. Doesn't really feel like I'm wearing anything, and isn't a problem if I want to layer it with something else. I do wash it off at night, and can tell that something is still on my face even at the end of the day because it's a little slippery when I wash it. So it has staying power.
For the price, I would definitely consider trying this product for moisturizing, and instantly smoother and softer skin.

plumping hydration with no greasiness or oiliness
Size: 1 Fl Oz (Pack of 1)
Its featherweight and melds with the skin in an instant. It plumps without any residue or "slip" on the skin. I have normal skin that tends toward slight dehydration and I use adapalene and the Ordinary 2% Salicylic acid anhydrous for my sebaceous hyperplasia. Because of the sebaceous hyperplasia and the heat and extreme humidity where I live, I cannot use anything with oils or dimethicone or anything even remotely occlusive. This serum is a great way for me to get appropriate hydration without exacerbating those enlarged oil glands or making my face sticky and oily. I dont need my face sealed, a humectant like this pulls plenty of hydration into my skin and I dont lose it to the air because of the ambient humidity. Its pretty perfect for me. It also has kept my barrier intact while alternating the adapalene and salicylic acid. Its a huge bang for the buck, I mean the price point is unbeatable.
