Hello VicW,
Unfortunately my first Jazz problem - also a seized rear brake caliper happened on Saturday last weekend at the beginning of what was to be a 500-mile return-trip, so very luckily it happened at the outset of my journey*.
Problem became apparent when slowing to a stop, slowing quicker than expected. Offside (right) rear wheel was warm to touch after only a very short (1-mile) journey into town. Found that applying a relatively heavy braking force, and vehicle would veer to left.
*Local Honda dealer (Sytner Gatwick) arranged a Courtesy car to allow me to continue my journey, so a big 'thank you' to them for their quick response.
However, the problem for me is that I've only had the car for 1 Month, purchased from above Honda dealer as an Approved Used Honda (Jazz 1.4 SE 2006, 58000 miles), and the Dealership have had to submit a detailed report back to Honda in order to claim for the work to be undertaken under the Approved Used Warranty. It transpires that the sudden failure is due to corrosion of the piston, and there is currently some doubt that the Approved Honda Warranty will cover this, and authority to order parts / undertake work hasn't yet been received (it's now Thursday).
I'd be grateful whether any other Jazz owners have any experience of this situation (particularly for corrosion issues under Approved Warranty), as my understanding on purchasing the vehicle (having not read the small-print in detail - yet) is that the Approved Honda Warranty covered the vehicle's main components and systems with the exception of consumable parts, such as brake-pads, battery, tyres, exhaust, fluids etc.
Not a very good start to Jazz ownership thus-far!
I thank you, and appreciate any advice that you can give.
Best regards,
Paul
