Mountain Buggy Nano™ Replacement Brake Kit | live price, prepared checkout
Built for shopping agents: what RoboTrunk does for every product
We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built.
RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product.
- Deep research: We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read.
check_productreturns them with a source for each. This product: 18 checked facts, research depth trimmed read, checked 2026-10-19T20:40:41.553Z, in the evidence pack. - Receipts: Every published fact has a receipt showing its source quote.
check_productandget_productreturn the checked facts that have one. This product: each checked fact listed below has one; the source quotes are in the evidence pack. - Safety:
check_productasks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. This product: this page holds no recall result for it yet;check_productasks the regulators now. - Recall watch:
watch_recallstells the buyer if a product bought here is recalled later. - Second-hand listings:
check_listingruns the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new. - The real price: The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on:
check_productandsearch_catalogtake the buyer's country and postcode. This product: this store's price was read from its catalogue at 2026-10-22T19:35:42.506Z. - A checkout that finishes: RoboTrunk lists only stores whose agent checkout it has verified.
create_checkoutprepares the order at the store;complete_checkoutreturns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs. - Markdown copy: Every page has a Markdown copy: this page's copy.
- Photos and ratings: Search results carry the product photo and, where the store's own page publishes one, its rating (
search_catalog). - Fit answers:
check_fitanswers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known. - Back-in-stock watches:
watch_back_in_stockstarts a watch on a listing the store shows as sold out;get_back_in_stock_watchshows when it is back in stock. - Maker's manual:
ask_product_manualanswers from the maker's manual with the exact passage and page, or says the manual does not cover it. - Tools and guide: Every tool and its description is at https://robotrunk.com/mcp; the guide is at /agents.md.
- Research from other stores: Coming soon: reading other stores' listings of the same product as new research sources.

Checked facts
Each fact below was checked against the source it cites before it was published. Each carries that source's link and the time RoboTrunk read it. 18 checked facts, checked 2026-10-19T20:40:41.553Z. Research depth: trimmed read. Deep read: the store's own data and 5 outside pages (the store's own product page; maker page; other; regulator recall search (CPSC (United States)); regulator recall search (Health Canada)), each read in full by RoboTrunk and trimmed to its main content, then written up and checked. Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read. Recall status was checked directly with CPSC (United States), Health Canada: The CPSC search for Mountain Buggy returned no recall records matching this kit. The Health Canada data contains one archived Mountain Buggy recall, for Breeze Strollers from 2005, which is a different product and does not apply to the nano replacement brake kit.

Questions we researched but could not confirm
Every fact above is cited. To find them we read the store listing, the maker's page, other pages about it and the recall records of CPSC (United States) and Health Canada and searched for the manual, regulator recall notices, owner reviews, blogs, owner forums and video reviews. We also chased the questions below across those sources and found no reliable answer, so you know exactly where the evidence ends and never have to guess.
- What exactly is included in the brake kit?
- Does the kit include both the left and right brake pedals?
- What material are the brake parts made of?
- Is the kit covered by a warranty?
- Will this kit also fit the Nano Duo?
- Is the listed 454 weight in grams or ounces?
- Do fitting instructions come in the box?
- Does the kit include a new brake cable?
- Is the finish painted, and can it wear or rub off?
- Are the replacement parts metal or plastic?

This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words.
